【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.更多还原

【Abstract】 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.更多还原
