摘要： 本文以碳纳米管(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、SnO2纳米粒子等3种形貌的SnO2纳米材料，研究了3种形貌的SnO2纳米材料对乙酸乙酯催化发光的影响；通过考察3种不同形貌SnO2纳米材料的纳米尺度和结构，讨论了影响纳米材料催化发光特性的因素；研究了3种不同形貌SnO2纳米材料对乙酸乙酯催化发光图谱和强度的变化，建立了3种新型、高效的不同形貌纳米催化发光传感器。

Abstract: SnO2 nanomaterials with three kinds of morphologies like nanoparticles, nanorods and SnO2-CNT nanocomposites were controllable synthesized using CNT as a template. Cataluminescence (catalytic chemiluminescence, CTL) characteristic of ethyl acetate catalyzed on nanosized SnO2 with 3 kinds of morphologies was studied. Nanostructure and BET　surface area of the SnO2 nanomaterial was very important for the CTL. A relationship between SnO2 nanomaterial with 3 kinds of morphologies and CTL of ethyl acetate was established. Three new kinds of gas sensors have been invented based on the spectrum mentioned above.

Key words: controllable fabrication, various morphologies, SnO2 nanomaterial, cataluminescence, ethyl acetate
