Development of Z-Scheme Photocatalyst Systems Combining Nonmetal Oxide Materials for Water Splitting under Visible Light Irradiation: (CuGa)0.5ZnS2 as a H2-Evolving Photocatalyst and TaON as an O2-Evolving Photocatalyst

Abstract

Z-Scheme System

The cover image represents water splitting into H₂ and O₂ via a Z-scheme system employing two photocatalyst materials. The electron transfer pathway, which resembles the shape of the letter “Z”, is highlighted. The originality of the present work lies in the development of a novel combination of photocatalyst materials for the Z-scheme system, utilizing reduced graphene oxide as a solidstate electron mediator.
