Abstract
A large number of power equipment work in closed or semi closed environment for a long time. Carbon monoxide (CO) is the highest concentration gas component in its fault discharge gas. Based on the Density functional theory of first principle, the adsorption behavior of CO gas molecule on intrinsic, Ag-doped hafnium disulfide (HfS2) monolayer was systematically studied at the atomic scale. Firstly, the intrinsic HfS2, Ag doped HfS2 (Ag-HfS2) monolayer with different doping sites were created. The most stable doping structure was selected to obtain the best performance of subsequent adsorbed gas. Then, the CO adsorption models of intrinsic HfS2, Ag-HfS2 were constructed and geometrically optimized. The results showed that Ag-HfS2 monolayer had good detection sensitivity and adsorption performance for CO. The research content of this paper provides a theoretical basis for the design and research of gas sensing materials based on HfS2, promoting the development and application of HfS2 in gas sensing and other fields.
