摘要

本文首次采用固态合成方法制备了锗酸铜(CuGeO3)混合贵金属钙钛矿氧化物。XRD证实材料为正交钙钛矿相。采用丝网印刷技术制备了CG厚膜。测试了厚膜对各种气体的气敏性能。当气体浓度小于10ppm时,对50℃的H2S气体具有最大的灵敏度。测量了传感器的灵敏度、选择性、响应和恢复时间。

Thick film of CuGeO3 as a H2S gas sensor
In this article, copper germanate (CuGeO3) mixed noble metal pervoskite oxide was prepared by solid-state synthesis process first time. XRD confirms the orthorhombic pervoskite phase of material. Thick films of CG were prepared by screen-printing technique. The gas sensing performance of thick films were tested for various gases. It showed maximum sensitivity to H2S gas at 50degC for less than 10ppm gas concentration. The sensitivity, selectivity, response and recovery time of the sensor were measured and presented.
