摘要
室温下在水溶液体系中,以非离子表面活性剂壬基酚聚氧乙烯醚和阳离子表面活性剂十六烷基三甲基溴化铵为模板,五水四氯化锡为无机前驱体合成介孔氧化锡,其孔径为2-10nm。通过N2-吸附/脱附、XRD、TG-DTA等检测手段对产物进行分析。通过控制壬基酚聚氧乙烯醚和十六烷基三甲基溴化铵的比例,可调节孔径的大小及比表面积等。
Tin-oxide with average pore size of 2 to 10nm was synthesized under room temperature in aqueous soltuion, using a cationic surfactant （cetyltrimethyl-ammonium bromide,CTAB） and non-ionic surfactant （nonylphenol polyethylene glycol ether,NP-10） as template and tin chloride as the precursor. The resultant products have been examined with N2-absorption/desorption, X-ray diffraction analysis （XRD）, and thermogravimetric analysis （TG-TDA）. The pore diameters of these mesoporous tin oxide materials changed by adjusting the molar ratio of cetyltrimethyl-ammonium bromide to nonylphenol polyethylene glycol with a certain range.
