V., “Tuning of Photocatalytic Performance of CeO2-Fe2O3 Composite by Sn-doping for the Effective Degradation of Methlene Blue (MB) and Methyl Orange (MO) dyes”, Surfaces and Interfaces, vol. 22, p. 100808, 2021.[Abstract]


One of the major class of pollutants used among textiles, medicines, plastics are organic dyes. Water pollution due to the industrial exhaust of large amount of these colouring materials are a major threat to our environment. Conventional methods of water treatment are not effective as these chemicals are not easily degradable. Sn-doped 1:2 CeO2-Fe2O3 nanocomposite with varying Sn content was prepared by thermal decomposition method for efficient degradation of MB and MO dyes under visible light. The phase composition and morphology were controlled by varying Sn content. 5% Sn doped 1:2 CeO2-Fe2O3 nanocomposite achieved nearly complete degradation for 10-50 mg/L MO solution and the maximum degradation efficiency obtained for MB solution is 93.54- 94.65 % for 10-30 mg/L MB solution. The optimized photocatalyst degraded MO more efficiently than MB solution. A smaller crystallite size of 12 nm was obtained. Incorporation of Sn4+ ions in CeO2 lattice improved the catalytic activity of CeO2-Fe2O3 composite by altering the fermi level of CeO2, facilitating charge separation. The influence of factors such as, exciton generation under solar irradiation, charge recombination rate, surface charge availability were illustrated. The long term stability and reusability of the catalyst composite towards photo degradation reaction unveil the industrial significance of the metal oxide composite.

The cathodic activity of Ni-P electrode for alkaline water electrolysis was enhanced by incorporation of CeO2-Al2O3 (Ce/Al) composite. The interaction of alumina in ceria was used for catalyzing HER on electroless deposited Ni-P in mild steel substrate. The crystallinity, size and optical characteristics of the composite were tuned by adjusting its composition during the synthesis process. The remarkable catalytic activity of Ni-P electrode with the present composite was due to superior stoichiometry of Ce (III) ions, which has resulted in an increase in oxygen vacancy concentrations and porous nature of the electrode surface. The enhanced stability of the prepared composite was achieved by changing the lattice parameter values of CeO2 lattice by its incorporation into Al2O3 lattice. The CeO2-Al2O3 (1:1 Ce/Al) composite incorporated Ni-P exhibited a very low overpotential of 61 mV compared to that of the bare Ni-P electrode (95 mV) at a current density of 10 mA/cm2. The high electroactive surface area of the composite incorporate coating is evident from the very high double-layer capacitance value of 3.23 × 10-3 F than the bare Ni-P electrode (3.8256 × 10-6 F). The modified Ni-P electrode is competent with other recently reported electrocatalysts for HER from alkaline solution.

TiO2/TiO2-WO3 (Ti/Ti-W) reinforced PANI hybrid composite synthesis and investigation of its structural and photocatalytic hydrogen evolution activity are discussed in the present work. The efficiency of the synthesized core/shell structured Ti/Ti-W in re-enforcing polyaniline, a conductive polymer with low band gap and enhanced visible light response for hydrogen evolution reaction is studied. Polyaniline supported mixed oxide composite is successfully fabricated by an in-situ polymerization reaction in presence of the as prepared composite. The interaction at the interface of the polymer and the oxide nanofiller in the resultant composite makes it a better visible light harvestor with significantly enhanced charge separation. The modified PANI/Ti/Ti-W composite yields 20.1 mL of hydrogen from 20 mL water containing 0. 1 g of diethyl amine hydrogen chloride with a quantum efficiency of 20.7%. The improved hydrogen delivering capacity offered by the polymer composite could be better explained in terms of effective utilization of solar energy, surface porosity and efficient separation of charge carriers. The mesoporous catalyst facilitated photocatalytic reaction by rapid diffusion, adsorption of reactants and by fast desorption of product molecules. The composite takes the advantage of both the organic and the inorganic components to achieve active hydrogen generation.

Ni-P coating (NPC) fabricated by electroless deposition has been widely accepted as an effective electrode for alkaline hydrogen evolution reaction. Among the different strategies reported to improve the catalytic activity of Ni-P electrode (NPE) further, incorporation of inorganic metal oxide composite is a proven method. Herein, we propose a modification of TiO2/TiO2-WO3 core-shell structured composite (a novel entity), by the application of conductive polyaniline (P-Ani), as a continuation of our earlier work on its synthesis and characterization. The as-prepared polymer-metal oxide hybrid nanocomposite is then employed to modify the NPE by electroless deposition method. The improved surface characteristics of the modified NPE, after the incorporation of P-Ani/TiO2/TiO2-WO3 composite with reduced charge transfer resistance and low overpotential for alkaline hydrogen evolution (−65mV at −10mA/cm2) corroborates its enhanced catalytic behavior. The increase in the number of catalytically active sites on the NPE after modification through P-Ani composite is attributed to the enhanced characteristics for alkaline hydrogen evolution. Our strategy proposes a sustainable and low-cost electrode material, competent to the existing industrial electrocatalysts, for long term hydrogen evolution in alkaline medium.

We, in our previous work, detailed the new design technology for the synthesis of novel TiO2/TiO2-WO3 core/shell composite (Ti/Ti–W) via the application of titanium turnings. Herein, we exploited the strategy with appropriate alternations to broaden the industrial significance of the method as well as the material. The work embodies a polyaniline assisted modification of Ti/Ti–W (0.1 g Ti metal/1:2 Ti–W) to develop a novel hybrid composite that has not yet been synthesized and studied. The composite was used to fabricate a sensing electrode for dopamine detection by electroless deposition from Ni–P bath. Cyclic voltammetric results revealed the sensing performance of Ni–P/PANI/Ti/Ti–W electrode towards dopamine detection. Further, differential pulse voltammetry (DPV) was employed to detect the sensing potential and sensing current, and the detection limit was found to be as low as 0.0037 μM with a sensitivity of 44.7 μA/μM cm2. The linear range of the optimized sensing electrode was 0.1–50 μM. Moreover, the electrode offered a remarkable detection of dopamine even in presence of other electroactive species such as AA, UA, NaCl and glucose. The real sample analysis explored Ni–P/PANI/Ti/Ti–W as a potential sensing electrode and can detect dopamine from urine sample with high sensitivity and accuracy. The obtained electroanalysis results confirm a 2H+/2e− mechanism of sensing in the developed electrode.

Electrically conducting polymer incorporated coatings effectively replaced chromate coatings, once widely employed for corrosion deterrence but now strictly restricted due to the environmental hazards. Here polyaniline nanocomposite was prepared by in situ polymerization of aniline monomer in presence of TiO2–WO3 powder, blended with PVC matrix and coated over mild steel specimens to evaluate its anti-corrosion property in alkaline environment. Structural parameters of the composites and coatings were obtained from XRD and SEM-EDS studies. Electrochemical parameters that govern the inhibitive efficiency of pigmented steel coupons were explored by Tafel polarization, electrochemical impedance spectroscopy, and open circuit potential measurements. The addition of (0.1 g) 1:1 TiO2–WO3 to PANI (polyaniline) improve the protective efficiency of PANI from 65% to 97.5%. PANI/TiO2–WO3 loaded specimen surface attained a state of passivity through uniform distribution of composite and characterized by the hydrophobic behavior that make it resistive to corrosive environment. Polarization studies identified the composite incorporated PANI as a mixed inhibitor. In order to extend the synthetic utility of prepared pigment, coated specimens are evaluated for their anticorrosive activity in acidic and mixed bacterial culture medium. The present work also included a detailed mechanism of passivation in view of the results of corrosion studies together with available literature studies. POLYM.

It is critical to develop highly tolerant, durable and efficient microbial corrosion inhibition methods for mild steel when use of chemical inhibitors is not feasible. Here, we developed a novel, long-lasting and commercially viable bacterial mediated corrosion inhibitive/biopassivating system for mild steel by employing Pseudomonas putida (P. putida) RSS biofilm. Enhancement in surface biopassivation was achieved by enhancing the biofilm formation in P. putida RSS culture when supplemented with 2.5% each of sucrose and potassium nitrate for a period of 96 h. The corrosion rate of mild steel could be decreased by 28 – fold when immersed in the optimized system in comparison to the control. This is due to the formation of a strong and stable iron-extracellular polymeric substance (Fe-EPS) coating over the concrete bacterial phosphate layer. The developed biofilm remained adhered on the surface of the mild steel surface even after the death of bacterial cells, and it conferred further protection. The corrosion resistance of mild steel surface after mechanically removing biofilm was also investigated. Results of electrochemical studies showed no traces of corrosion even after 12 months of immersion with negligible corrosion rate of 3.01 × 10−2 mmpy. The developed surface biopassivation system can be employed for long term corrosion inhibition of steel structures in aquatic systems

The present paper reports about the superior performance of some amine-based proton sources in enhancing the photocatalytic efficiency of Fe2O3–TiO2 composite during a water-splitting reaction. The band gap of the Fe2O3–TiO2 catalyst is tuned to 2.3 eV by varying the Fe content. The heterojunctions generated in the photocatalyst facilitate effective charge carrier migration suppressing the electron–hole recombination rate. The enhanced photocatalytic activity of the catalyst is studied using an experimental setup comprising a solar simulator (AAA) and a hydrogen gas chromatograph. The effect of proton sources viz, aniline hydrogen chloride (AH), diethylamine hydrogen chloride (DAH) and triethylamine hydrogen chloride (TAH), on the photocatalytic performance of the catalyst is explored and studied in detail. These proton sources serve as electron donors that stimulate photogenerated electron–hole separation that results in high quantum efficiency of the Fe2O3–TiO2 photocatalyst. A very high hydrogen generation rate of 880 μmol h−1 is achieved with the DAH-assisted Fe2O3–TiO2, whereas it is just 323 μmol h−1 with the Fe2O3–TiO2 alone. The enhancement in the hydrogen generation rate is attributed to the high basic nature, distinct hole scavenging action, low electron–hole recombination rate and the swift interfacial charge – transfer process. The effect of other proton source-assisted catalysts are also discussed in detail.

An efficient TiO2 core/TiO2–WO3 shell structured nanocomposite is successfully synthesized by a method of acid precipitation followed by thermal decomposition. The metal weight ratio of TiO2–WO3 is optimized in order to achieve visible-light absorption. We made the mixed-oxide composite on titanium metal turnings in order to enhance the active surface area available for water-splitting reaction. The novelty of the present work mainly lies on the utterly different approach that we adopt for tuning of the composite with titanium turnings as the major material. The structural and morphological changes in the mixed oxide on the turnings are characterized in detail based on X-ray diffraction, Fourier transform infrared, transmission electron microscopy, scanning electron microscopy–energy-dispersive X-ray analysis, and Raman spectroscopy. The enhanced surface properties are evaluated based on Brunauer–Emmett–Teller adsorption. The band-edge position, band gap, and range of light absorption are envisaged by UV–visible spectroscopy. The photocatalytic activity of the composite is evaluated under visible-light irradiation. The volume of hydrogen gas evolved during water-splitting reaction is quantified after confirming the purity of the evolved hydrogen by gas chromatography. The mechanism of the enhanced water-splitting process by the fabricated photocatalytic system is then depicted. An appreciable quantity of pure hydrogen is produced by the catalyst composite, the stability and reproducibility of which is further ascertained by different experiments.

Purpose
This paper aims to evaluate the inhibitive action of different concentrations of Sesbania grandiflora leaf extract on the mild steel corrosion in an aggressive HCl medium under different experimental conditions.
Design/methodology/approach
Weight loss investigation, open-circuit voltage analysis, Tafel polarisation, AC impedance analysis, etc. were used for the evaluation of inhibition efficiency. The influence of immersion period on inhibition efficiency was evaluated. The mechanism of action of the inhibitor is also discussed. Infrared (IR) spectroscopy and energy-dispersive X-ray spectroscopy analysis were used to characterise the passive film.
Findings
The results suggested that 10,000 ppm solution has maximum inhibition efficiency of 98.01 per cent at room temperature, while 1,000 ppm solution also exhibited a better efficiency of about 96.16 per cent. Efficiency of inhibitor solution was found to increase with an increase in its concentration. Polarisation study proposed the solution as an anodic inhibitor. Impedance study confirmed the formation of a protective layer over the surface of the specimen, and the constituents of the film were identified using IR spectroscopy. Stability of the film adsorbed on the steel was cleared from the steady open-circuit potential value. Study on action of the inhibitor under accelerated conditions revealed the fact that the efficiency of extract in preventing corrosion is good under stimulated conditions also.
Practical implications
The action of inhibitor sustains for a sufficient time period and could sustain under stimulated conditions. Hence, its application is practically possible in industries. The proposed inhibitor is widely available and is environmentally safe.
Originality/value
HCl is an industrially important chemical used for acid cleaning, acid pickling, etc. HCl was used as an aggressive corrosion environment. As the chances for mild steel to be in contact with HCl were very high, it was important to develop an efficient, economical and eco-friendly inhibitor for corrosion.

Yield of hydrogen production was increased to 583.7 μ mol h-1, when the reaction was carried out in presence of t-butanol. It worked as an efficient hole scavenger and reduced the electron-hole pair recombination rate. The efficiency of action of applied sensitizers in the rate of hydrogen production was t-butanol ˃ iso-propanol ˃ methanol.

Composite incorporated Ni-P electrodes were fabricated for alkaline water electrolysis. The effect of (Polyaniline) PANI-TiO2 polymer composite in hydrogen evolution efficiency of Ni-P electrode in NaOH medium was studied. Characterization of the composites was carried out by XRD and coating composition was confirmed by EDS analysis. Catalytic action of the fabricated electrodes was analysed by polarization and electrochemical impedance spectroscopic techniques. The optimized electrodes exhibited a lower overpotential value of 139 mV for hydrogen evolution reaction at 200 mA cm-2. The composite incorporated electrodes achieved enhanced catalytic activity as a result of improved active sites, increased surface roughness and decreased resistance for electron transfer reaction in comparison with pure Ni-P electrode.
