Selective Cocatalyst Deposition on ZnTiO3−xNy Hollow Nanospheres with Efficient Charge Separation for Solar‐Driven Overall Water Splitting

Pt and RhOx cocatalysts are selectively deposited at inner and outer surface of ZnTiO3−xNy hollow nanospheres, respectively. The resulting photocatalytic systems exhibit promising activity for photocatalytic overall water splitting with stoichiometric H2/O2 ratio under simulated solar insolation. Se...

Description
Summary:Pt and RhOx cocatalysts are selectively deposited at inner and outer surface of ZnTiO3−xNy hollow nanospheres, respectively. The resulting photocatalytic systems exhibit promising activity for photocatalytic overall water splitting with stoichiometric H2/O2 ratio under simulated solar insolation. Selective deposition of Pt and RhOx cocatalysts at different surfaces not only mitigates back reactions of the products but also induces strong potential gradient within nanospheres that promotes efficient dissociation and fast migration of photocarriers to the surface. Overall water splitting is achieved on ZnTiO3−xNy hollow nanospheres with selective deposition of Pt and RhOx. Deposition of Pt and RhOx at inner and outer surface not only mitigates back reactions of the products but also induces strong potential gradient that promotes efficient dissociation and fast migration of photocarriers to the surface.
