“…In this study, Ag 2 O and CuO were adopted to modify MoSe 2 for indoor harmful C 6 H 6 and HCHO gas detection. Referring to studies discussing the effect of modification quantity on gas sensitivity of MoSe 2 substrates, bimolecular modification enabled a better stable structure and gas sensitivity. Therefore, this study carried out double Ag 2 O and CuO modification on the MoSe 2 substrate. The adsorption characteristics and gas-sensing mechanism of Ag 2 O- and CuO-modified MoSe 2 (TMO–MoSe 2 ) to indoor hazardous C 6 H 6 and HCHO gasses were investigated based on density functional theory (DFT), which has been widely verified to be an effective way to research the surface adsorption properties of the nanomaterials. Through structure optimization, adsorption energy, and band structure analysis, this study provides a theoretical method to evaluate the influence of transition metal modification on the gas-sensing performance for C 6 H 6 and HCHO detection in the indoor environment. …”
