| Abstract |
Developing a photocatalysis system to generate hydrogen from water is a topic of great interest for fundamental and practical importance. BiVO4 Photocatalyst has suffered by the slow charge separation kinetics at solid/electrode interface that limits the photoelectrochemical performance (PEC). In order to minimize the poor properties, we modified the BiVO4 IO photocatalyst with an effective silver Plasmonic Nano structure which was examined under light illumination. Silver Nano structure scatter propagating Plasmon’s into photons in which light is coupled between BiVO4 IO and silver metal. As a results the photonic crystal properties with the formation of a plasmonic band gap leads to a red shift in the electrode that allows harvesting and generating a larger portion of solar spectrum. The well-defined size, smooth surface and high crystallinity of silver Plasmon’s facilitates fast electron transport to the photoelectrode. |
