| 要約: | Title screen Inspired by the structure of molybdenum-based metalloenzymes with high CO2 conversion efficiency in nature, the catalytic performance of a series of modified MoN4 for two-electron CO2 reduction reaction (CO2RR) was systematically studied using first-principles calculations. The effect of 20 p-block elements as axial ligands on the structure of MoN4 was evaluated. Benefiting from the significant effect of the axial ligands on the adsorption strength of Mo for intermediates, both activity and selectivity were improved, especially Ge-MoN4 exhibited the best performance in the formic acid (HCOOH) pathway. The orbital hybridization between Mo and the intermediate was weakened to varying degrees by axial ligands. Furthermore, the activity of the catalysts was related to the properties of the axial ligands, especially the Mo-N bond length and the electronegativity difference between Mo and the axial ligands. This work provides a thorough understanding and guidance for modifying the coordination environment of single-atom catalysts for CO2RR Текстовый файл AM_Agreement |
