Electrocatalytic Hydrogenation Boosted by Surface Hydroxyls‐Modulated Hydrogen Migration over Nonreducible Oxides
University of Science and Technology of China · National Synchrotron Radiation Laboratory
Abstract
Abstract The migration of atomic hydrogen species over heterogeneous catalysts is deemed essential for hydrogenation reactions, a process closely related to the catalyst's functionalities. While surface hydroxyls‐assisted hydrogen spillover is well documented on reducible oxide supports, its effect on widely‐used nonreducible supports, especially in electrocatalytic reactions with water as the hydrogen source, remains a subject of debate. Herein, a nonreducible oxide‐anchored copper single‐atom catalyst (Cu 1 /SiO 2 ) is designed and uncover that the surface hydroxyls on SiO 2 can serve as efficient transport channels for hydrogen spillover, thereby enhancing the activated hydrogen coverage on the catalyst and…
