摘要:
以片状的Bi_2MoO_6为前驱物,通过原位化学沉淀法制备了Bi_2MoO_6/Ag_3PO_4复合光催化剂,考察了其光催化降解罗丹明B(RhB)的活性。研究表明:Bi_2MoO_6和Ag_3PO_4复合可显著提高光催化活性,Bi_2MoO_6和Ag_3PO_4匹配的能级结构有利于光生电子和空穴的分离,延长光生载流子的寿命;当Bi_2MoO_6的质量分数为35%时,复合光催化剂具有最佳的光催化活性。
摘要(英文):
The Bi2MoO6/Ag3PO4 composites were prepared via in-situ chemical deposition of Ag3PO4 on the surface of plate-like Bi2MoO6. The photocatalytic activities were evaluated by the degradation of Rhodamine B (RhB) under visible light irradiation. The experimental results show that the coupling of Bi2MoO6 with Ag3PO4 can improve the photocatalytic activity, and the 35% Bi2MoO6/Ag3PO4 composite exhibits the optimum photocatalytic performance. The possible mechanism of the enhanced photocatalytic activity is ascribed to the well-matched energy bands of...
