摘要
以硝酸银为原料,水为反应介质,聚乙烯吡咯烷酮为保护剂,甲酸铵作为还原剂,利用普通液相还原法常温一步直接制备得到平均粒径在10nm左右的纳米级银粉。采用XRD、EDS、TEM等测试手段,对所制得的纳米银粉进行了表征。并简要讨论了纳米银粉制备过程中的各类影响因素。
Through the method of liquid reduction at room temperature, the nano-silver powders （averaging diameter 10 nm） were prepared directly using silver nitrate as raw material, water as the reactive medium, polyvinyl pyrrolidone （ PVP ） as protecting agent and ammonium formate as reducing agent. By means of XRD, EDS and TEM, the prepared silver particles were characterized. Then the various influencing factors in the process of preparation were also discussed briefly.
