Preparation and application of high-response zinc cobaltate/indium sesquioxide composite gas-sensitive material

The invention discloses preparation and application of a high-response zinc cobaltate/indium sesquioxide composite gas-sensitive material, and belongs to the technical field of gas sensors. The preparation method of the high-response zinc cobaltate/indium trioxide composite gas-sensitive material comprises the following steps: uniformly mixing a ZnCo2O4 precursor and an In2O3 precursor, and sintering at high temperature to obtain the high-response zinc cobaltate/indium trioxide composite gas-sensitive material. The zinc cobaltate/indium sesquioxide composite gas-sensitive material has the advantages of high selectivity, high sensitivity, low working temperature and the like, solves the problems of high working temperature and low detection sensitivity of the existing metal oxide gas-sensitive sensing material, and provides important theoretical significance and practical application value for research, development and utilization of novel gas-sensitive sensing materials. 本发明公开了一种高响应钴酸锌/三氧化二铟复合气敏材料的制备及应用，属于气体传
