Abstract : In this work Nickel-Aluminium layered double hydroxide (LDH) was successfully synthesized via urea hydrolysis method. This involves the digestion of aluminium sulphate, nickel sulphate and urea at 90 ⁰C for 24 hours. Atomic force microscopic (AFM) studies revealed the presence of highly ordered layers and the Ni-Al LDH was observed to be in the hexagonal cubic crystalline structure through X-ray diffraction studies. The prepared compound was utilized for fabrication of a non-enzymatic electrochemical glucose sensor. Glucose oxidation on the sensor occurred at 0.6 V in 0.1 M NaOH. The sensor exhibited a sensitivity of4.12 µA/mM/cm2 with linearity upto28 mM. The developed sensor was sensitive towards glucose in the presence of common interfering molecules such asascorbic acid, uric acid, dopamine and creatinine.
