模板法制备纳米介孔二氧化锆的研究

Reseach on the mesoporous nano-zirconia by template method

本实验分别以十六烷基三甲基溴化铵、三乙醇胺、酵母为模板剂,以氧氯化锆为无机锆源,以氨水为沉淀剂,通过共沉淀法和煅烧法制备介孔二氧化锆,用比重瓶法测比重、用BET氮气吸附法测试介孔二氧化锆的比表面积、测试了样品的电导率,得出十六烷基三甲基溴化铵为模板剂优于三乙醇胺和酵母的结论。

Mesoporous Zirconia is synthesized by the law of co- precipitation and calcinations, which used Cetyltrimethyl Ammonium Bromide（CTAB）, Triethanolamine and Yeast as template medicinal preparation respectively; used Zirconium Oxychloride as the source of the abiozirconium, and the Ammonia as the precipitator. The conclusion was that Cetyhrimethyl Ammonium Bromide（CTAB） surpassed Triethanolamine and Yeast for template medicinal preparation by measuring the proportion with the density bottle method, the specific surface area of the Mesoporous Zirconia with the BET nitrogen adsorption law and the electrical conductivity of the sample.
