研究了水热处理醋酸银（CH 3COOAg）制备粒径分布均匀的银纳米粒子（AgNPs）的影响因素。研究了反应时间和醋酸银溶液浓度对银纳米粒子合成的影响，并对产物进行了表征。CH 3COOAg的水热水处理在间歇式反应器中在250 - 450 °C的温度之间进行。在超临界水区域，在400 °C和31.5 MPa的压力下，由于超临界水的低介电常数下的反应速率增加，银颗粒被快速合成。制备的银颗粒的尺寸为30-80 nm，通过XRD和TEM观察鉴定，显示出高度结晶的结构。
Hydrothermal water treatments of silver acetate (CH3COOAg) were investigated to reveal the factors controlling the formation of silver nanoparticles (AgNPs) with uniform size distribution. The effects of reaction time and concentration of silver acetate solution on the synthesis of Ag nanoparticles were studied, and the fabricated products were characterized. The hydrothermal water treatments of CH3COOAg were carried out between the temperatures of 250 - 450 °C in a batch reactor. In supercritical water regions, at 400 °C and a pressure of 31.5 MPa, silver particles are rapidly synthesized due to reaction rate increases at a low dielectric constant of supercritical water. The preparation of the silver particles with 30-80 nm in size showed a highly crystalline structure identified by XRD and TEM observations.
