摘　　要：针对纳米银合成的关键,形貌和粒径大小的控制,研究了把硝酸银溶解在乙腈中,以聚乙烯吡咯烷酮(PVP)为稳定剂,在溶剂热条件下反应制备纳米银。初步研究了不同反应温度(100、120、140℃)和不同PVP浓度对纳米银粒径大小和形貌的影响。初步结果表明反应温度升高,得到的纳米银趋向于单形貌;PVP浓度增加,纳米银粒径减小。The control over size and morphology is important for the synthesis of silver nanoparticles.In this study,silver nanoparticles stabilized by PVP were prepared by acetonitrile solvothermal.The particle size and morphology influenced by different reaction temperature and different concentration of PVP were preliminarily studied.The results indicate that higher temperature facilitates to the formation of single morphology nanoparticles and higher concentration of PVP produces smaller ones.
