以十二烷基苯磺酸钠（SDBS）和对苯二甲酸为表面活性剂，在乙醇和水的混合体系中合成了氧化锡（SnO 2）空心纳米球。系统的研究表明，对苯二甲酸在空心纳米球的形成中起着关键作用。在目前的工作中，合成的SnO 2空心纳米球表现出优异的室温乙醇敏感性和对乙醇的电氧化的潜在催化能力，因此有望成为经济的替代催化剂，并在工业应用中，如室温气体传感器有用。（© Wiley-VCH Verlag GmbH & Co. KGaA，69451魏因海姆，德国，2006）
Tin oxide (SnO2) hollow nanospheres have been successfully synthesized from mixed ethanol and water systems containing the surfactants sodium dodecyl benzenesulfonate (SDBS) and terephthalic acid. Systematic studies reveal that terephthalic acid plays pivotal roles in the formation of hollow nanospheres. In the present work, the as-synthesized SnO2 hollow nanospheres exhibit excellent room-temperature ethanol sensitivity and potential catalytic ability towards the electrooxidation of ethanol, and thus are expected to be economical alternative catalysts and useful in industrial applications such as room-temperature gas sensors.
