采用沉淀法制备了AgCl与Cu2+共存的纳米水溶胶,油酸萃取并包覆AgCl与Cu2+共存的纳米水溶胶,制备了AgCl与Cu2+共存的纳米有机溶胶,对水溶胶和有机溶胶的制备条件进行了系统的研究。TEM分析表明,AgCl纳米粒子呈球形,粒径约50nm,粒度分布均匀,无明显团聚现象。ED分析表明,AgCl纳米粒子为多晶结构,其中有少量的单晶存在。表面包覆油酸的AgCl纳米粒子易溶于弱极性溶剂,难溶于极性溶剂。
The nano-aqueous sol with coexistence of AgCl and Cu2 + was prepared by precipitation method. The nanosized sol with coexistence of AgCl and Cu2 + was obtained by oleic acid extraction. The nano-organosol with coexistence of AgCl and Cu2 + was prepared. The preparation conditions of aqueous sol and organosol The systematic research. TEM analysis showed that the AgCl nanoparticles were spherical with a size of about 50 nm, with uniform particle size distribution and no agglomeration. ED analysis shows that the AgCl nanoparticles are polycrystalline with a small amount of single crystal present. Surface coated with oleic acid AgCl nanoparticles soluble in weakly polar solvents, insoluble in polar solvents.
