Abstract : Development of two-dimensional (2D) layered nanomaterials of bismuth oxyhalides (BiOCl, BiOBr, and BiOI) has attracted considerable interest due to the renewable energy conversion. A new class of 2D layer semiconductor materials and tunable morphologies enhance the photocatalytic reactions. The dominant {001} facet engineering structures and bandgap controlling can be achieved by changing the stoichiometry ratios of the precursor solution. Synthesis of polymer composite thin films and fabrication methods involve free-standing flexible films, which are used as a dip photocatalyst for degradation of pollutants. 2D nanomaterials and surface-interaction engineering modification with noble metal nanoparticles establish hybrid nanostructures. The hybrid nanostructures enhanced the light absorption property through the plasmonic effect-induced “hot electrons” that improve the conductivity of the materials and are used in photodetector and surface-enhanced Raman scattering applications. The bandgap of the 2D layer nanomaterial was controlled by modulating the thickness and concentration of the precursor element. 2D layer structures of bismuth oxyhalides are a promising avenue for featured diverse technologies and wide applications in electronics, optoelectronics, photodetectors, and photovoltaics.
