Preparation and Application of Heterogeneous Photocatalysts Based on New Cross-Linked Polymers

以苯乙烯(S)和二乙烯基苯(DVB)为原料,采用端基为2-巯基-S-硫代苯甲酰乙酯的聚乳酸(PLA)作为链转移剂,同时加入具有光催化功能的含氟硼二吡咯(BODIPY)的苯乙烯(BDP-St)单体,通过可逆加成-断裂链转移(RAFT)聚合技术来制备交联聚合物,然后通过氢氧化钠甲醇/水溶液选择性刻蚀掉交联聚合物上的PLA链段,从而制备出高分子非均相光催化剂,并对其光催化氧化甲基苯基硫醚的性能进行研究.结果表明,所得到的聚合物材料没有明显的孔结构,但是光催化实验发现,采用含有PLA的链转移剂得到的聚合物的催化性能要优于小分子链转移剂,但PLA的含量对光催化性能的影响不大.
