First-principles calculations are conducted to investigate the Nb-doped PtS2 (Nb-PtS2) monolayer for sensing C2H2 and C2H4 in the on-load tap-changer of the oil-immersed transformers. The adsorptions of two gases on the Nb-PtS2 monolayer are verified as chemisorption with adsorption energies of-2.47 and-1.0.91 eV, as confirmed by Hirshfeld analysis, charge density difference and orbital density of state. The band structure indicates the good sensing response of 1206.7% and-4717.4%, for C2H2 and C2H4 detections, suggesting its strong potential as a resistance-type gas sensor for their detections. This work paves the ways to explore novel PtS2-based gas sensor effectively.
