摘要
通过水热法成功合成出ZnS/AlPO-5复合材料,采用XRD(X-射线粉末衍射)、DRUV-Vis(紫外-可见漫反射光谱)、XPS(X-射线光电子能谱)、BET(比表面分析)等技术对其进行理化性能表征,并以亚甲基蓝(MB)溶液为目标降解物,评价了其在可见光作用下的光催化性能。结果表明,该复合材料对亚甲基蓝表现出良好的可见光光催化性能,在80ml质量浓度为10mg/l的亚甲基蓝溶液中加入0.1g催化剂,可见光辐照5h时,脱色率(DC)可达97.5%;辐照24h的矿化率可达90%以上。
ZnS/AlPO-5 composite was prepared by hydrothermal synthesis method. Its physicochemical properties were characterized by means of XRD, DR UV-Vis, XPS and BET. Its photocatalytic activity was evaluated by photodegradation of methylene blue (MB) under visible-light irradiation. The results showed that ZnS/AlPO-5 composite possessed well visible-light photocatalytic activity. Under visible-light irradiated 5 h, the decolorization rate (DC) of 80 ml 10 mg/1 MB solution went up to 97.5%, and its mineralize rate of 24 h was over 90%.
