吡啶对含硫四氮杂钴卟啉光催化性能的影响

摘要

The immobilized photocatalyst cobalt thioporphyrazine CoPz(HOCH2-dtn)4/resin was prepared. Its adsorption-desorption properties for RhB and degradation of RhB under light illumination were studied.The effect of pyridine on its photocatalytic degradation of RhB was investigated as well.Results showed that,the ad-sorption-desorption equilibrium for RhB was reached in 2 h and the adsorption rate was about 1 5%.The addi-tion of pyridine could promote photocatalytic performance of CoPz(HOCH2-dtn)4/resin significantly by axial coordination with the central metal cobalt.%制备了负载型含硫四氮杂钴卟啉光催化剂CoPz(HOCH2-dtn)4/resin,研究了其对罗丹明B(RhB)的吸附脱附性能、光照下对 RhB的降解作用及吡啶对其光催化降解 RhB的影响。结果表明,负载型催化剂对 RhB在2 h内达到吸附脱附平衡,吸附率为15%左右；催化剂能较好地催化 RhB的降解,吡啶分子能与催化剂中心金属钴轴向配位,对其光催化活性起到了明显的促进作用。
