摘要 采用银纳米粒子为催化剂,研究了银纳米粒子对硝基苯甲酸还原的催化性能。结果表明,纳米尺度的银粒子在室温下可极大地加速对硝基苯甲酸的还原过程。其中,银纳米粒子被认为起着电子媒介体作用,即还原剂硼氢酸根优先将电子传递到银纳米粒子,继而吸附的对硝基苯甲酸获取电子发生还原。 Catalytic reduction of p-nitrobenzoic acid was investigated on silver nanoparticles. The reduction process of p-nitrobenzoic acid can be greatly accelerated in the presence of nanosized silver metal at room temperature. The silver nanoparticles may function as the electron mediator to transfer the electrons from borohydride to p-nitrobenzoic acid.
