|
Abstract:
通过一步水热法制备出MoS2/Sb2S3可见光复合催化剂，采用XRD、SEM、紫外可见漫反射（UV-Vis DRS）和XPS表征手段对MoS2/Sb2S3复合光催化剂进行了表征，以罗丹明B（RhB）作为目标污染物进行降解实验。与纯Sb2S3和MoS2相比，MoS2/Sb2S3复合光催化剂对RhB的光催化降解具有更高的效率，表现出优异的吸附性能和光催化性能。同时在相同的实验条件下，与TiO2、Bi2S3、C3N4、Sb2S3等催化剂相比，MoS2/Sb2S3复合光催化剂表现出更为优异的光催化性能。此外，探究了MoS2/Sb2S3复合光催化剂光催化降解机制，阐述了光催化反应机制，提供了一种适用于降解较高浓度有机废水的光催化剂制备方法，具有一定的应用价值。 Visible light responsive MoS2/Sb2S3 composite photocatalyst was successfully designed and constructed by a simple one-step hydrothermal process. XRD, SEM, UV-vis diffuse reflectance spectroscopy (UV-Vis DRS) and XPS were used to characterize its photocatalytic activity. The degradation experiment was conducted with rhodamine B (RhB) as the target pollutant. Compared with the pure Sb2S3 and MoS2, the MoS2/Sb2S3 composite photocatalyst exhibits highly enhanced efficiency in the degradation of RhB, showing excellent adsorption performance and photocatalytic performance. Compared with TiO2, Bi2S3, C3N4 and Sb2S3, MoS2/Sb2S3 composite photocatalyst is possessed as more excellent photocatalyst under the same experimental conditions. In addition, the photocatalytic degradation mechanism was carried on the exploration. This research expounds the mechanism of photocatalytic reaction, and provides a application for the photocatalyst preparation methods of degradation high concentration organic wastewater, which has certain application value. 国家科技重大专项项目（2016ZX05040003
