Hydrogen is a promising source of energy that is receiving much attention as an alternative for fossil fuels. Photoelectrochemical (PEC) water splitting emerged as a sustainable technology for hydrogen production. In this approach, the solar energy is utilized in presence of metal oxide semiconductors to split water into oxygen and hydrogen. In this presentation, we describe the synthesis and characterization of bismuth vanadate (BiVO4) with dual heterojunction and demonstrate its enhanced photocatalytic activity for the degradation of organic dyes. BiVO4 nanocrystals are doped with bismuth oxyhalides and palladium nanoparticles and studied as photoanode for the photoelectrochemical oxygen generation from water splitting. This will ultimately create p-n heterojunction material that improves the charges separation, which results in enhanced photoelectrochemical water splitting. This novel composite has demonstrated high photocurrent in alkaline solution under visible light irradiation that indicates enhanced water splitting.
