Selective CO₂ Photoreduction into CH₄ Triggered by the Synergy between Oxygen Vacancy and Ru Substitution under Near-Infrared Light Irradiation.

ABSTRACT: Near-infrared (NIR) light powdered CO₂ photoreduction reaction is generally restricted to the separation efficiency of photogenerated carriers and the supply of active hydrogen (*H). Herein, the study reports a retrofitting hydrogenated MoO_3-x (H-MoO_3-x) nanosheet photocatalysts with Ru single atom substitution (Ru@H-MoO_3-x) fabricated by one-step solvothermal method. Experiments together with theoretical calculations demonstrate that the synergistic effect of Ru substitution and oxygen vacancy can not only inhibit the recombination of photogenerated carriers, but also facilitate the CO₂ adsorption/activation as well as the supply of *H. Compared with H-MoO_3-x, the Ru@H-MoO_3-x exhibit more favorable formation of *
