摘要
通过水热法制备纳米银颗粒,制备过程使用聚乙烯吡咯烷酮(PVP)作保护剂,柠檬酸钠(C6H5Na3O7·2H2O)作还原剂,还原硝酸银溶液得到纳米银颗粒。通过控制反应时间以探究制备纳米银所需的最佳时间,并通过投射电子显微镜(TEM)、Malvern粒度分析仪(Size&Zeta)、紫外吸收光谱(UV-Vis)等分析手段对制备的纳米银的结构形态进行表征。
Silver nanoparticles were prepared byhydrothermal method using polyvinylpyrrolidone(PVP) as a protective agent and sodium citrate(C6H5Na3O7·2H2O) as a reducing agent through reducing silver nitrate solution. The reaction time was controlled to explore the optimal reaction time required for preparation of silver nanoparticles. Moreover, the structure and morphology of prepared silver nanoparticles were characterized by transmission electron microscope(TEM), Malvern particle Size analyzer(Size & Zeta), ultraviolet absorption spectrum(UV-Vis) and other analytical methods.
