摘要：

以Mo O3、Cd0.5Zn0.5S、聚乙烯吡咯烷酮为原料,水热一锅法制备了Cd0.5Zn0.5S/Mo O3复合材料,通过XRD、XPS、SEM、UV-VisDRS及PL对复合材料的结构、形貌以及光学性能进行了表征。在可见光照射下,将其用于甲基橙（MO）、罗丹明B、亚甲基蓝、孔雀石绿、酸性品红、结晶紫的光催化降解。结果表明,Mo O3/Cd0.5Zn0.5S复合材料对上述染料都具有光催化降解能力,其中,对MO的光催化活性最佳。可见光照射60 min,质量浓度0.67 g/L的10%Cd0.5Zn0.5S/Mo O3(Cd0.5Zn0.5S含量为10%,以Mo O3质量计)对质量浓度10 mg/L MO的降解率达到98.0%,表观速率常数为0.06725 min–1,分别约为MoO3和Cd0.5Zn0.5S的172倍和31倍。
