摘要 为制备粒径较小、分布均匀、稳定的纳米银溶胶,以月桂酸钠为保护剂,水合肼为还原剂,硝酸银溶液为前驱体,采用化学还原法进行试验。试验结果表明,保护剂与还原剂的用量对纳米银的粒径有着较大的影响。当保护剂用量为0.5 g、水合肼用量为1.0 g时,所得到的纳米银粒子平均粒径为5~7 nm。 In order to prepare stable silver nanoparticles with narrow distribution, a simple route in water was used, with sodium laurate as the protecting agents, hydrazine hydrate as reducing agents, silver nitrate solution as precursor. The results showed that the dosage of the protecting agents and reducing agents play an impor- tant role in the formation of small size silver nanoparticles with narrowly distribution. Well - dispersed silver anopartilces with average diameter of 5 to 7 nm were obtained when the dosage of protecting agents was 0.5 g and the dosage of reducing agents was 1.0 g.
