摘要
本文采用碳纳米管(CNT)为模板,通过液相沉积法可控合成了一维SnO2纳米材料:SnO2-CNT纳米复合材料、SnO2纳米棒,均匀规则的一维SnO2纳米棒仅仅通过改变煅烧SnO2-CNT纳米复合材料的反应温度获得。这两种一维纳米材料可以显著改善纳米表面气-固相催化发光性能,阐明了纳米材料的比表面积、结构与其催化发光的关系,建立了一种新型的一维SnO2纳米材料催化发光的乙醇传感器。
A simple method for controllable fabrication of one - dimension SnO2 nanocomposites and SnO2 nanorods by carbon nanotube (CNT) - templated with liquid phase deposition has been proposed. SnO2 - CNT nanocomposites were made of the CNT coated by a thin layer of SnO2 nanoparticles. Uniform and monodispersed crystalline SnO2 nanorod has been obtained by burning of SnO2 - CNT nanocomposites. The controllable synthesis of one - di- mension SnO2 nanomaterials with two kind nanostructures has been achieved by simply changing reaction tempera- ture. A relationship between onedimension SnO2 nanomaterial and Cataluminescence (catalytic chemiluminescence, CTL) of ethanol were established. Both the obtained SnO2 nanocomposites and SnO2 nanorods shows the improved properties in CTL of ethanol. Based on the spectrum mentioned above, a new kind of gas sensors has been invented.
