Among the distinctive energy choices for future, the one that holds an unequivocal edge over others is the 'Hydrogen'. It tends to be delivered in huge sums by photograph parting of water utilizing richly accessible sunlight based radiations. With zero carbon release, hydrogen is a totally spotless and naturally generous fuel. The current proposal manages concentrates on PEC parting of water utilizing as photoelectrode four distinctive material frameworks, each addressed by a bunch of bi-layered nano-hetero-organized flimsy movies as WO3 (under layer) – ZnO (over layer) BaTiO3 (under layer) – ZnO (Over layer) WO3 (under layer) – TiO2 (over layer) and BaTiO3 (under layer) – TiO2 (Over layer). Studies on PC parting of water were likewise attempted, utilizing as photocatalyst two arrangements of nano-heterostructured powder tests as ZnO (center) – Ag doped TiO2 (shell) and CuO (center) – Ag doped TiO2 (shell). In the PC parting of water methanol was utilized as conciliatory specialist to search openings and forestall recombination. Tests were portrayed by X-beam Diffractometer, UVVisible Absorption Spectrometry, Scanning Electron Microscopy, Atomic Force Microscopy, Tunneling Electron Microscopy, BET Surface Area Determination, Electron Dispersive X-Ray Analysis and Flat Band Potential Determination. Contrasted with unblemished examples, the bi-layered dainty movies yielded huge addition in PEC photocurrent. Bi-layered movies with WO3 under layer showed generally higher photocurrent contrasted with films with BaTiO3 under layer. Center shell nano-hetero-organized powder tests likewise end up being better and more proficient photocatalyst for water parting against the immaculate examples of single metal oxide. Among the two material frameworks examined, CuO (center) – Ag doped TiO2 offered moderately higher hydrogen yield. This framework was likewise examined under field conditions utilizing constant sunlight based brightening. Conceivable clarifications have been given PECPC execution of the considered material frameworks.
