Defects‐Induced Single‐Atom Anchoring on Metal–Organic Frameworks for High‐Efficiency Photocatalytic Nitrogen Reduction

Abstract Aiming to improve the photocatalytic activity in N 2 fixation to produce ammonia, herein, we proposed a photochemical strategy to fabricate defects, and further deposition of Ru single atoms onto UiO‐66 (Zr) framework. Electron‐metal‐support interactions (EMSI) were built between Ru single atoms and the support via a covalently bonding. EMSI were capable of accelerating charge transfer between Ru SAs and UiO‐66, which was favorable for highly‐efficiently photocatalytic activity. The photocatalytic production rate of ammonia improved from 4.57 μmol g −1 h −1 to 16.28 μmol g −1 h −1 with the fabrication of defects onto UiO‐66, and further to 53.28 μmol g −1 h −1 with Ru‐single atoms loading. From the…
