Hydrogen energy production and dyes degradation have been considered the need of modern age of technology in globe irrespective of the level of science and research in that country. Hydrogen gas is a green energy fule for the future application and abunduntly available in environment. Various techniques are reported for the production of hydrogen energy among which photocatalysis method is envirnmental friendly, cost-efficient method using water that also decontaminated from dyes, which is a main problem nowadays because of increase in industrial applications according to the living standards. The composite of Bismuth vanadate (BiVO4) with the coupling of the rduced graphene oxide (rGO) were synthezied by the facial hydrothermal technique by using a bismuth nitrate penta hydrate and amonium metavanadate as main precour and graphene oxide solution for reduced graphene oxide incorporation. X-ray diffraction (XRD), Scanning Electron Microscope (SEM), ultraviolet adsorption spectroscopy (UV-vis), and Brunauer-Emmett-Teller (BET) characterization tools investigate the role of concentration of the coupling material rGO in BiVO4. All characterization techniques confirms that 1.5% rGO/BiVO4 shows transformation of tetragonal to monoclinic phase with altration of the particles size (25-40 nm), with high-surface area, having irregular spherical porous clusters degradation of methelene blue (97%), production of green energy in the form of hydrogen gas fuel, and enhancement of the absorption of light that is clear intimation of the high photocatalytic efficiency towards the decontamination of the wastewater and production of hydrogen gas. Prepared nanostructured composite in current work reveals effective photocatalytic activity for decontamination of the wastewater and evolution of hydrogen energy would be the precise idea to utilize them in near future with various promising applications.
