摘　　要：聚乙烯吡咯烷酮(PVP)络合Pd2+后,负载于聚乙二醇(PEG)功能化的Al2O3柱支撑后的膨润土(Al-PRT)上,制备了催化剂PVP-PdCl2/Al-PRT-PEG,并用于催化不溶于水的对氯甲苯水相脱氯.实验表明该催化剂呈现出较高的脱氯活性和重复使用功能.用IR,XRD等手段表征了Al-PRT,并探讨了催化剂各组分在催化脱氯反应中的作用.A novel catalyst PVP-PdCl2/Al-PRT-PEG was prepared through supporting the PVP （polyvinglpyrrolidone）-archored Pd^2＋ on Al-PRT （Al2O3-pillared bentonite） function-allied by PEG （polyethylene glycol）. It has shown better dehalogenetion activity and reusability for catalyzing dechlorination of insolvable p-chlorotulunce in agueous system. The Al-PRT has been characterized by IR,XRD. The effect of each catalyst＇s composition in dechlorination reaction is discussed.
