Z-scheme photocatalytic hydrogen production over WO3/g-C3N4 composite photocatalysts†
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.
