    "description": "An excellent single-atomic photocatalyst, Ti@C\u2084N\u2083, is theoretically found to effectively convert CO\u2082 to C\u2082H\u2086 by density functional theory (DFT) calculations and non-adiabatic molecular dynamics (NAMD) simulations. The Ti@C\u2084N\u2083 photocatalyst has remarkable stability both thermally, chemically, and mechanically. Electronically, it has strong absorption properties, suitable band positions, and a long photogenerated electron lifetime, allowing photogenerated electrons to migrate to the surface. Notably, the high-valence active site effectively activates two CO\u2082 through dual activation: Under light irradiation, the weakly adsorbed CO\u2082 undergoes photo-induced activation by the photoelectron of conduction band minimum (CBM); without light, the high Lewis acidity of the Ti site induces CO\u2082 activation through back-donating \u03c0-bond. Contrast simulation results uncovered that dual activation of CO\u2082 is attributed to the thermal and photonic synergy. Furthermore, two activated CO\u2082 species under light easily couple to form oxalate with the barrier of 0.19 eV, and further reduced to C\u2082H\u2086 with a low activation energy of 1.09 eV.",
