Hydroxyl-Bonded Ru on Metallic TiN Surface Catalyzing CO 2 Reduction with H 2 O by Infrared Light
Fuzhou University · King Abdullah University of Science and Technology
Abstract
Synchronized conversion of CO2 and H2O into hydrocarbons and oxygen via infrared-ignited photocatalysis remains a challenge. Herein, the hydroxyl-coordinated single-site Ru is anchored precisely on the metallic TiN surface by a NaBH4/NaOH reforming method to construct an infrared-responsive HO-Ru/TiN photocatalyst. Aberration-corrected high-angle annular dark-field scanning transmission electron microscopy (ac-HAADF-STEM) and X-ray absorption spectroscopy (XAS) confirm the atomic distribution of the Ru species. XAS and density functional theory (DFT) calculations unveil the formation of surface HO-RuN5–Ti Lewis pair sites, which achieves efficient CO2 polarization/activation via dual coordination with the C…
