Abstract: High Resolution Image Download MS PowerPoint Slide The development of sensitive gas sensors for O 3 detection is a promising approach to enable early monitoring of air-insulated switchgears (AIS). This work employing first-principles theory investigates the adsorption behaviors and sensing potential of pristine, Pt-, and Au-PdS 2 monolayers in response to O 3 molecules. First, the Pt- and Au-doping properties on the pristine PdS 2 monolayer are illustrated. Besides, through the analysis of adsorption parameters and electronic properties, the role of noble metal doping in enhancing gas-sensing performance of PdS 2 -based materials is elucidated. Moreover, the impact of humidity for further promoting the O 3 gas-sensing performance of three monolayers is uncovered. The findings highlight the potential of Pt- and Au-PdS 2 monolayers as highly promising resistive gas sensors upon O 3 detection. It is expected that our work will inspire further experimental research on PdS 2 -based materials with the aim of exploring their practical applications in gas sensing across a wide range of fields.
