摘要: 本文采用简单的水热法通过在MoO3纳米带表面上负载MoS2颗粒成功地获得了MoS2/MoO3复合催化剂。产物通过XRD、SEM、EDS等手段进行表征，结果显示，MoS2/MoO3复合物由MoO3纳米带表面负载MoS2纳米颗粒组成。产物的光催化性能测试表明，MoS2/MoO3复合物展示了比单体MoS2和MoO3更优异的降解RhB特性，在60 min的可见光照射下降解率可达到75%，对应的降解速率常数为0.02304，这种更好的可见光催化活性来自于MoS2/MoO3复合结构中电子与空穴的快速分离。
Abstract: In this paper, MoS2/MoO3 composite catalyst was successfully obtained by uploading MoS2 particles on the surface of MoO3 nanobelts via a simple hydrothermal method. The products were characterized and analyzed by XRD, SEM, and EDS techniques. The results showed that MoS2 na-noparticles were loaded on the surface of MoO3 nanobelts for MoS2/MoO3 composite. The photo-catalytic performance test showed that MoS2/MoO3 composite has the better degradation effects of RhB than MoS2 and MoO3. The degradation rate can reach 75% under visible light irradiation in 60 min, and the degradation rate constant is 0.02304. This good catalytic activity under visible light came from the rapid separation of electrons and holes in the MoS2/MoO3 composite.
