中文摘要:
      为了解决均相keggin型锰取代杂多阴离子PW11O39Mn(II)(H2O)5-[ PW11Mn]光催化剂在 水溶液中难以回收利用的问题,选用D301R弱碱性阴离子交换树脂对其进行吸附,制备了PW11Mn/ D301R光催化材料。通过有机染料亚甲基蓝(MB)的可见光降解反应考察了PW11Mn/D301R材料 的光催化性能。实验表明,PW11Mn/D301R在可见光照射下对MB有较高的光催化降解活性。此 外,还系统考察了溶液中有其他阴离子存在时对光催化降解效果的影响,并提出了作用机制。本 研究为高效利用太阳能去除水体有机染料污染物提供了一条新颖途径。
英文摘要:
      :Keggin type Mn(II) substituted heteropolyanion PW11O39Mn(II)(H2O)5-[PW11Mn] was adsorbed onto D301R resin to resolve the separation of catalysts in the homogeneous system. The photodegradation of the organic dye methylene blue (MB) was carried out to evaluate the visible light photocatalytic activity of PW11Mn/D301R. The experimental results showed that the heterogeneous system PW11Mn/D301R had high photocatalytic activity for visible light degradation of MB. In addition, the effects of other ions in the solution on photocatalytic degradation were systematically investigated, and the mechanism of photocatalytic reaction was proposed. This research provided a novel way to efficiently utilize sunlight to re⁃ move organic dye contaminants from water.
