采用AOT(二-乙基己基琥珀酸酯磺酸钠)为表面活性剂,以正庚烷为油相,以四氯化锡为前驱物,采用油包水型微乳液法制备了纳米SnO2颗粒,并借助XRD、 DTA-TG、 FTIR、 SEM等手段系统研究了制备温度、AOT质量、溶液pH值等因素对产物性能的影响.本实验体系中的最佳工艺参数为:pH=8,水-表面活性剂摩尔比1∶2, AOT质量0.6 g,锻烧温度600℃,保温时间2 h.在最佳试验条件下所制备的SnO2粉末平均粒径为4.1 nm,较常规沉淀法制备的SnO2颗粒细小且团聚少,具有更好的性能.

Nanoparticles of tin oxide ( SnO2 ) have been prepared from water-in-oil ( W/O) micro-emulsions consisting of SnCl4 , water, AOT, and n-heptane.The effects of calcination temperature, AOT contents and pH values of solution on the properties of products were studied by XRD, DTA-TG, FTIR and SEM.Results show that the optimal condition in the system is:pH value of the solution was 8, the molar ratio of water to AOT was 1 ∶2, the content of AOT was 0.6 g and the products was calcined at 600℃for 2 h.The tin oxide powder was found to be less than 4.1 nm in particle diameter and to be more disperse than it prepared by the chemical precipitation method.
