Abstract:
The present invention relates to developing a simple, cost-effective and green approach to structure-controlled heterostructures consisting of heteroatom-doped  graphene nanosheets supported on bismuth ferrite using low-cost hydrothermal process for water splitting under visible light irradiation at room temperature. Control  morphologies of the heteroatom doped graphene nanosheets (GNS) bismuth ferrite (BFO) heterostructures achieved by low-cost hydrothermal process. Doping of  heteroatom on the surface of graphene allows tuning the band gap of bismuth ferrate in the range of 2.05 to 2.2 eV resulting in good visible light absorption and highly  efficient for solar-to-chemical energy H2 conversion via photocatalytic water splitting. The heteroatom doped graphene nanosheets supported BFO heterostructures are  useful as photoanode for photoelectrochemical water splitting and green hydrogen (H2) production.
