摘　　要：借助电喷雾辅助化学还原法,直接在室温下,将氯酸金前体溶液的分散气溶胶喷射到含有还原剂(ODAM)和环己烷非极性溶剂(POCH)的反应溶液中来合成单分散小尺寸纳米金粒子。将电喷雾喷射分散进料与传统毛细管连续进料方法进行比较,通过动态光散射(DLS)和扫描透射电子显微镜(STEM)等对合成的纳米金进行表征,结果证明电喷雾辅助化学还原法是一种快速通用合成单分散金纳米粒子(AuNPs)的新方法。By electrospray-assisted chemical reduction method,directly in non-polar solvent at room temperature,The elec-trospray technique was used to spray a dispersed aerosol of gold precursor [gold (Ⅲ) chloride hydrate] into the reaction bath containing reducing agent (octadecylaminomethanol) and non-polar solvent (cyclohex-ane). Two methods of reagent incorporation into the reaction bath were compared: incorporation by continuous stream flow using a capillary,and by continuous fine droplet flow using electrospray technique. The obtained Au NPs were characterized by DLS,and scanning transmission electron microscopy (STEM). Results confirmed this is a fast and versatile method of monodisperse gold nanoparticles (AuNPs)synthesis.
