Analysis of the sensing performance of Ag-doped Ti3C2O2 MXene for characteristic gases in transformer oil
Using the DMol3 module of Material Studio, first-principles calculations were performed to analyze the sensing performance of Ti3C2O2 and Ag-doped Ti3C2O2 for dissolved gases in oil. Research data indicate that the adsorption energies of Ti3C2O2 for CO before and after Ag doping are −0.232 eV and − 1.194 eV, respectively. The introduction of Ag enhances charge transfer from CO gas to the material, thereby improving the adsorption performance of the material for CO. The adsorption energies for CO2 on Ti3C2O2 and Ag-Ti3C2O2 are −0.329 eV and − 0.320 eV, respectively. For CH4, these values are −0.278 eV and − 0.370 eV, respectively.
期刊介绍:
Chemical Physics publishes experimental and theoretical papers on all aspects of chemical physics. In this journal, experiments are related to theory, and in turn theoretical papers are related to present or future experiments.
