Efficient Electrocatalytic Oxidation of Glycerol via Promoted OH* Generation over Single-Atom-Bismuth-Doped Spinel Co 3 O 4

The renewable electricity-driven electrocatalytic oxidation of biomass represents a pathway to produce value-added chemicals from waste biomass such as glycerol (a byproduct of industrial biodiesel production). However, it remains difficult to design an efficient electrocatalyst with explicit structure–property relationships. Herein, we report a single-atom bismuth (Bi)-doping strategy to endow Co3O4 with enhanced activity and selectivity toward electrocatalytic glycerol oxidation reaction (GOR). Experimental characterizations and theoretical calculations reveal that single-atom Bi substitutes cobalt at octahedral sites (CoOh3+) in Co3O4, facilitating the generation of reactive hydroxyl species (OH*) at…
