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 spillover well documented on reducible oxide supports, its effect widely‐used nonreducible especially in electrocatalytic reactions with water as source, remains subject debate. Herein, oxide‐anchored copper single‐atom catalyst (Cu 1 /SiO 2 ) designed and uncover that hydroxyls SiO can serve efficient transport channels spillover, thereby enhancing activated coverage favoring reaction. Using dechlorination model reaction, Cu delivers hydrodechlorination activity 42 times greater than commercial Pd/C. An integrated experimental theoretical investigation elucidates facilitate intermediates formed at sites, boosting active . This work demonstrates feasibility acting hydrogen‐species boost supports paves way designing advanced selective electrocatalysts.
