摘要

采用热蒸发气相沉积法

以An为催化剂成功制备了Ce3+掺杂的SnO2纳米带。用X射线衍射（XRD）、扫描电子显微镜（SEM）、光电子能谱（EDX）对样品的形貌、结构和成分进行了表征分析。结果表明:Ce3+掺杂的SnO2纳米带具有金红石结构

纳米带表面光滑、平整

结晶良好

其成分由Ce

Sn和O构成。同时

研究了单片Ce3+掺杂的SnO2纳米带对丙酮、乙醇和乙二醇的气敏特性

发现温度为190℃时器件对乙二醇气敏响应最强

选择性也最好。Ce3+掺杂的SnO2纳米带对乙二醇响应、恢复时间短

可逆性好

适合在较宽浓度范围对乙二醇气体进行检测。

Abstract

Ce3 +-doped SnO2（ Ce-SnO2） nanobelts are prepared successfully by thermal evaporation. The obtained sample is characterized by X-ray diffraction（ XRD）

scanning electron miroscope（ SEM）

and energy dispersive X-ray spectroscopy（ EDX）. The results reveal that the Ce3 +-doped SnO2 nanobelts have rutile structure

smooth surface

good crystallization

synthesized Ce3 +-doped SnO2 nanobelt is composed of Ce

and O. Gas sensitive responses to acetone

ethanol and ethandiol of single chip Ce3 +-doped SnO2 nanobelt are researched

and it is found that when operating temperature is 190 ℃

gas sensitive response of the device to ethanediol is the strongest and selectivity is the best. The response and recovery time is short

and reversibility is good

which is suitable for ethandiol detection at a wide range of concentration.
