采用银纳米粒子作催化剂,研究其对催化硝基化合物反应速率的影响,结果表明,纳米银粒子在室温下可极大地加速对硝基化合物的还原过程,带正电荷的硝基化合物比带负电荷的硝基化合物具有更高的催化反应速率;催化剂银粒子越多,反应速率越大,但因受纳米粒子本身性质的制约,数量不能无限大;催化剂银粒子粒度越小,反应速率越大。 Silver nanoparticles were used as catalysts to study their effects on the catalytic rate of nitro compounds. The results show that the silver nanoparticles can greatly accelerate the reduction of nitro compounds at room temperature. The positively charged nitro compounds are more negative than those with negative charges Charged nitro compounds have a higher catalytic reaction rate; the more the catalyst silver particles, the greater the reaction rate, but due to the nature of the nanoparticles themselves, the quantity can not be infinite; the smaller the catalyst silver particle size, the greater the reaction rate .
