摘　　要：以碳纳米管(CNT)为模板,采用液相沉积法,通过改变煅烧温度可控合成了SnO2-CNT复合纳米材料、SnO2纳米棒2种形貌的纳米材料,研究了该2种纳米SnO2材料对甲基叔丁基醚(MTBE)的催化发光(CTL)特性,由此制备了基于SnO2纳米材料的气-固表面催化发光传感器,并利用SnO2纳米棒催化发光传感器测定了汽油中MTBE的体积分数。结果表明,SnO2纳米棒催化发光传感器测得的汽油样品的MTBE体积分数与采用气相色谱法测得结果的相对误差小于5%,但它具有快速、方便、运行成本低的优点。SnO2 nanomaterials with two kinds of morphologies,SnO2-CNT nanocomposites and SnO2 nanorod,were controllable synthesized with CNT as a template.Cataluminescence（Catalytic chemiluminescence,CTL） characteristic of methyl tert-butyl ether（MTBE） on SnO2-CNT nanocomposites and SnO2 nanorod was studied.A new kind of CTL sensor was prepared based on the CTL mentioned above and used to determine the volume fraction of MTBE in gasoline product.Compared with GC method,the relative error of the MTBE volume fraction in gasoline product was less than 5% determined by SnO2 nanorod CTL sensor with the advantages of rapid,convenient and low running cost.
