| 摘 要： | 通过磷钨酸H3PW12O40(HPW)和邻菲啰啉C12H8N2(Phen)的溶液反应,合成了杂多化合物(C12H8N2)2.5H3PW12O40((Phen)2.5HPW),以WO3空心微球为载体,负载杂多化合物(Phen)2.5HPW,制备了(Phen)2.5HPW/WO3复合空心微球.用等离子体原子发射光谱(ICP-AES)、元素分析(EA)、热重-差热分析(TG-DTA)、傅里叶变换红外光谱(FTIR)、扫描电子显微镜(SEM)、紫外-可见漫反射吸收光谱(UV-vis DRS)对样品进行了表征.在高压汞灯照射下,研究了杂多化合物(Phen)2.5HPW、WO3空心微球和(Phen)2.5HPW/WO3复合空心微球对甲基橙水溶液的光催化降解活性,结果表明,(Phen)2.5HPW/WO3复合空心微球的光催化活性高于单独的杂多化合物(Phen)2.5HPW和WO3空心微球,催化剂易于回收,光催化性能稳定.
