以导电玻璃为电极超声电解合成纳米银溶胶的研究

Sonoelectrochemical Synthesis of Silver Nanoparticle Colloids with ITO Electrode

以导电玻璃为电极,超声电解合成了一系列不同外观颜色的纳米银溶胶。结果表明,纳米银溶胶的外观颜色与电解电压和PVP的浓度有关;超声是合成稳定纳来银溶胶的一个不可少的条件;紫外-可见吸收光谱分析表明,不同电解电压和PVP浓度得到的纳米银溶胶的形貌和粒径大小也不同;透射电镜分析表明,纳米银颗粒的粒径随PVP浓度的增大而减小。

A series of silver nanoparticle colloids with different color was synthesized by sonoelectrochemical method with ITO（Indium Tin Oxides） electrode.Ultrasonic was required during the preparation of stable nano-silver colloids.The size and shape of the silver nanoparticle colloids changed with the electrolysis voltage and the concentration of PVP.TEM and UV-Vis results showed the particle size was decreased with increase of the concentration of PVP.
