This study investigates the adsorption and detection performance of transition metal Co-modified WS2 for typical SF6 decomposition products (H2S, SO2, and SOF2). The research reports the reaction mechanism based on first-principles density functional theory (DFT), including adsorption energy, band structure, charge density difference (CDD), density of states (DOS), and molecular orbital aspects. Furthermore, the desorption performance is combined to further explore the practical application possibilities. The results demonstrate that Co-modified WS2 significantly enhances the adsorption performance of H2S, SO2, and SOF2 to strong chemical adsorption.

摘要

This study investigates the adsorption and detection performance of transition metal Co-modified WS2 for typical SF6 decomposition products (H2S, SO2, and SOF2). The research reports the reaction mechanism based on first-principles density functional theory (DFT), including adsorption energy, band structure, charge density difference (CDD), density of states (DOS), and molecular orbital aspects. Furthermore, the desorption performance is combined to further explore the practical application possibilities. The results demonstrate that Co-modified WS2 significantly enhances the adsorption performance of H2S, SO2, and SOF2 to strong chemical adsorption.
