Abstract

WO₃/g-C₃N₄ composite photocatalysts were prepared by a simple calcination method and H₂ production activity of these composites was evaluated. The photocatalytic activity of the composites highly depended on WO₃ content. The enhanced photocatalytic activity could be ascribed to the Z-scheme mechanism, which results in the efficient charge separation.
