摘要
以PVP为分散剂,用乙二醇作溶剂和还原剂,在溶剂热条件下还原AgNO3,得到了球形和棒形的纳米银。透射电镜分析表明,PVP用量对纳米银粒径的影响要比对形貌的影响更大,PVP用量越多,得到的纳米银颗粒粒径越小;紫外-可见光谱分析证实了纳米银的生成。
Silver nanosphere and nanorod were synthesized by ethyleneglycol, AgNO3 reduced with PVP as stabilizer. TEM analysis show that the higher the content of PVP, the larger size of silver nanoparticles is produced;UV-Vis testified the synthesis of nanosilver.
