    摘要:

    采用微乳液法制備超細(xì)In2O3粉體，粉體粒徑為8nm，在In2O3基體材料中摻雜Pd及金屬氧化物，研制出實(shí)用性的熱線型C2H5OH氣敏元件，該元件功耗低(小丁300mW)，選擇性高，長(zhǎng)期穩(wěn)定性好。并考察了溫度、濕度變化對(duì)氣敏元件性能的影響，分析了元件的氣敏機(jī)理。

    Abstract:

    The sensitive composite material was prepared by doping Pd and some metal oxides into ultrafine In2O3 matric material(8 nm) prepared by microemulsion method. A kind of selective C2H5OH gas sensor was developed based on a hot wire type gas sensor commercially available. The sensor possesses low power consumption , high selectivity and desirable long term stability. The dependence of the sensor output characteristics on temperature and humidity was also studied, and the working mechanism was discussed.
