An efficient g-C3N4/BiVO4 heterojunction photocatalyst is constructed with BiVO4 networks decorated by discrete g-C3N4 nano-islands with controllable coverage. The as-synthesized g-C3N4/BiVO4 photo-catalyst shows superior visible light photocatalytic activity. The enhanced photocatalytic activity can be ascribed to increased charge separation efficiency, separated redox reaction sites, fully exposed reactive interfaces, and excellent visible light response of g-C3N4/BiVO4 composite.
一种高效的 g-C3N4/BiVO4 异质结光催化剂是通过在离散的 g-C3N4 纳米岛上可控覆盖 BiVO4 网络构建的。所合成的 g-C3N4/BiVO4 光催化剂表现出优异的可见光光催化活性。增强的光催化活性可归因于增加的电荷分离效率、分离的氧化还原反应位点、充分暴露的反应界面以及 g-C3N4/BiVO4 复合材料的优异可见光响应。
