摘要
制备了负载型含硫四氮杂钴卟啉光催化剂CoPz(HOCH_2-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2h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。
The immobilized photocatalyst cobalt thioporphyrazine CoPz（HOCH_2-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 adsorption-desorption equilibrium for RhB was reached in 2h and the adsorption rate was about 15%.The addition of pyridine could promote photocatalytic performance of CoPz（HOCH_2-dtn）4/resin significantly by axial coordination with the central metal cobalt.
