Abstract

The effectiveness of reduced graphene oxide as a solid electron mediator for water splitting in the Z-scheme photocatalysis system is demonstrated. We show that a tailor-made, photoreduced graphene oxide can shuttle photogenerated electrons from an O₂-evolving photocatalyst (BiVO₄) to a H₂-evolving photocatalyst (Ru/SrTiO₃:Rh), tripling the consumption of electron - hole pairs in the water splitting reaction under visible-light irradiation.
