摘要
以PVP为表面活性剂和保护剂,甲酸铵为还原剂,在室温条件下液相还原硝酸银制备纳米银。用X射线衍射(XRD)、透射电子显微镜(TEM)、紫外-可见(UV-Vis)吸收光谱对产物进行表征。结果表明,通过调控PVP表面活性剂的用量,在室温条件下可制备不同形貌、不同分散性的纳米银。
Silver nanoparticles were synthesized under room temperature with polyvinyl pyrrolidone(PVP) as stabilizer and ammonium carbamate as reductant.The as-prepared nanoparticles were characterized by XRD,TEM and UV-Vis.The results indicated that the shape and dispersity of silver nanoparticles were controlled by the dosage of PVP.
