摘要
报道了利用溶剂热工艺在乙醇溶液中制备胶态纳米金属钌颗粒的方法。在120℃热处理不同时间后,观测到溶剂热还原反应形成不同颜色的中间体。通过添加醋酸根稳定剂,在乙醇溶剂中形成晶粒尺寸为3～6纳米的单分散金属钌颗粒。通过该方法还合成了溴化十六烷基三甲铵(HTAB)包敷的晶粒尺寸为1～5纳米的金属钌粉体。
Alcohothermal process for the preparation of metallic Ru nanoparticles in the ethanol solution is described. The solvothermal reaction shows different colors during the heat treatment at 120 ℃ at different reaction times. Monodispersed ruthenium colloidal nanoparticles with a diameter of 36 nm in the ethanol solution were obtained by adding acetate ions as a stabilization reagent. Ru powders composed of 15 nm particles capped by hexadecyltrimethylammonium bromide (HTAB) were also synthesized by this method.
