摘　　要：主要介绍了纳米银的制备以及核壳结构Ag@SiO_2纳米球的制备,并对核壳结构的Ag@SiO_2的性质进行了测试和表征。选择乙醇作为溶剂,使用改进的St?ber法和化学液相还原法制备纳米银和Ag@SiO_2纳米球,并对其影响因素进行了探究。In this paper, the preparation of silver nanoparticles and the preparation of Ag @ SiO2 nanoparticles core - shellstructure were introduced. The properties of Ag @ Si02 were tested and characterized. Silver nanoparticles and Ag @ SiO2nanoparticles were prepared by improved St？ ber method and chemical reduction in liquid phase, and solvent is ethanol. And theinfluence factors Ag@ Si02 nanoparticles were explored in this paper.
