摘　　要：以Dawson结构的磷钨酸和缺位Keggin结构的硅钨酸为配体合成了铜复合微米材料,分别研究其结构形貌,并作为催化剂催化硼氢化钠还原对硝基苯酚、邻硝基苯酚和间硝基苯酚和铁氰化钾,结果表明,两种催化剂都能高效地催化还原反应,经比较其速率常数,基于硅钨酸合成的铜微米复合材料具有更高的催化活性.Two novel polyoxometalate-based Cu micro-hybrid materials P2W18-Cu and SiW9-Cu were synthesized in this paper.After investigated the mophology and the structure,these two materails were used as catalyst in the reduction of nitrophenols and potassium ferricyanide.The result indicated that both P2W18-Cu and SiW9-Cu could be treated as the high effectient catalyst in the reduction,in comparison,the SiW9-Cu exhibted much higher catalytic activity.
