Abstract

Bimetallic Au Ag nanoparticles, prepared using sodium borohydride as the sole reducing and capping agent for various NaBH : metal molar ratios, were investigated as catalysts for 4-nitrophenol reduction. This approach yielded the highest catalytic activities observed for this model reaction to date.

摘要

使用硼氢化钠作为唯一的还原剂和封端剂，针对不同的硼氢化钠与金属摩尔比制备了双金属金 银纳米颗粒，并将其作为4-硝基苯酚还原反应的催化剂进行了研究。对于该模型反应，此方法产生了迄今为止所观察到的最高催化活性。
