To further improve the charge separation and photocatalytic activities of g-C3N4 and CdMoO4 under visible light irradiation, CdMoO4/g-C3N4 composites were rationally synthesized by a facile precipitation-calcination procedure. The crystal phases, morphologies, chemical compositions, textural structures, and optical properties of the as-prepared composites were characterized by the corresponding analytical techniques. The photocatalytic activities toward degradation of rhodamine B solution were evaluated under visible light irradiation. The resu...

半导体光催化技术因其能够完全矿化和降解废水以及废气中的各种有机和无机污染物而受到越来越多研究者关注.尽管TiO_2作为光催化剂显示了良好的应用前景, 但其只对紫外光响应, 该部分能量大约仅占太阳光谱的5%, 从而限制了其实际应用. 因此, 开发新型可见光响应光催化剂成为光催化领域的研究焦点之一. 石墨相氮化碳(g-C_3N_4)作为一种光催化材料, 由于具有良好的热和化学稳定性以及可见光响应而备受关注. 然而, 单纯的g-C_3N_4由于光生电荷载流子易复合,光催化效果并不理想. 为进一步提高g-C_3N_4的光催化活性, 构建g-C_3N_4基异质结复合光催化材料被认为是增强g-C_3N_4光生电子-空穴分离效率的...
