Photocatalysis: Interfacing BiVO₄ with Reduced Graphene Oxide for Enhanced Photoactivity: A Tale of Facet Dependence of Electron Shuttling (Small 38/2016)

Excellent photoelectrochemical performance of bismuth vanadate in water splitting is achieved by coupling with graphene sheets. On page 5295, R. Amal, S. C. Smith, Y. H. Ng, and co-workers, demonstrate the ability to achieve efficient interfacial charge transfer between bismuth vanadate and graphene sheets by modulating the exposure extent of {010}/{110} facets of bismuth vanadate. The overall photoactivity is governed by the quality of bismuth vanadate-graphene interfaces. These findings would be useful in guiding the development of efficient photoelectrochemical sensors, photo-induced hydrogen generation, and solar cells.
