Abstract: The research on H2S–sensing materials, such as SnO2, ZnO, ZnS, WO3 and composite metal oxide is summarized. The effects of dopant and preparation method on promoting the sensitivity and selectivity, lowering working temperature, and shortening response time and recovery time are discussed. Based on the domestic and overseas research status in this field, the development trend of gas sensors is presented.
