摘要:
为解决摄入高浓度乙醇对身体健康产生的危害，并且乙醇蒸汽与空气混合在高温环境下容易发生爆炸的问题，以十六烷基三甲基溴化铵为结构指导剂，在水热条件下合成了铜（Cu）掺杂的二氧化锡（SnO2）树叶状纳米材料，通过X射线衍射、扫描电子显微镜以及X射线光电子能谱对材料进行表征。气敏测试结果表明：当铜掺杂量为摩尔分数2% 时，这种SnO2对乙醇的气敏响应最佳。具体表现为：在250 ℃的工作温度下，对体积分数为1×10-6乙醇的响应值（Ra/Rg）高达139.65，较纯SnO2传感器材料的响应值提高了近5倍。此外，该材料还对乙醇表现出良好的选择性，这主要是由于这种材料表面具有丰富的表面吸附氧。此项研究表明合理的元素掺杂是提升气体敏感性能的一种有效策略。

Abstract:
High concentration of ethanol causes great harm to people’s health， and the ethanol vapor mixed with air may explode at high temperature. In this study， we used a hydrothermal method to synthesize the Cu-doped leaf-like stannic oxide （SnO2） nanomaterials，through using hexadecyl trimethyl ammonium bromide as structural guide. The prepared materials were characterized by X-ray diffraction， scanning electron microscopy and X-ray photoelectron spectroscopy. The experiment results show that the SnO2 nanostructure has the best gas sensing response to ethanol when the amount of Cu doping is 2%. The specific performance is as follows： at the working temperature of 250 ℃， the response value to 1×10-6 ethanol is up to 139.65， which is about 5 times higher than that of pure SnO2 sensor materials. In addition， the synthesized material also shows good selectivity for ethanol， which is due to the rich surface adsorption oxygen on the surface of this material. This study shows that reasonable element doping is an effective method to improve gas sensitivity.
