摘要:

以SnCl4·5H2O为原料,聚乙二醇(PEG-1000)作为分散剂,利

用沉淀法制备出SnO2纳米粉体,采用扫描电镜(SEM)和X-射线衍射

(XRD)对其形貌和微观结构进行表征.并以其作为基底材料以离子的

形式掺杂摩尔比为1%的Ni2+作为气敏材料,制作掺杂和未掺杂两种

旁热式气敏元件,测试其对乙醇、甲醇和丙酮的气敏特性.发现在较

低的工作温度下两种元件对三种气体都有较高的敏感性,同时Ni离

子的掺杂对三种气体的灵敏度有不同的影响,对乙醇表现出很好的

选择性.

Abstract:

Nanometer SnO2 powder was prepared by

precipitation using SnCl4·5H2O as raw materials and PEG

—1000 as dispersant, the morphology and microstructure

were characterized by SEM and XRD. The indirect heating

gas sensors were prepared using nanoSnO2 and nano

SnO2 doped by metallic ions Ni2+. Gas sensitivity of the

sensor to ethanol, methanol and Acetone was studied. The

results show that two sensors has high sensitivity to

the three gases. Meanwhile, the Ni addition have

different effect on the gas sensitivity to the three

gases, and good selectivity to ethanol.
