Active Hydroxyl‐Mediated Preferential Cleavage of Carbon‐Carbon Bonds in Electrocatalytic Glycerol Oxidation

Abstract Electrocatalytic glycerol oxidation reaction (GOR) to produce high‐value formic acid (FA) is hindered by high formation potential of active species and sluggish C−C bond cleavage kinetics. Herein, Ni single‐atom (Ni SA ) and Co single‐atom (Co SA ) dual sites anchored on nitrogen‐doped carbon nanotubes embedded with Ni 0.1 Co 0.9 alloy (Ni 0.1 Co 0.9 @Ni SA Co SA ‐NCNTs) are constructed for electrochemical GOR. Remarkably, it can reach 10 mA cm −2 at a low potential of 1.15 V versus the reversible hydrogen electrode (vs. RHE) and realize a high formate selectivity of 93.27 % even at high glycerol conversion of 98.81 % at 1.45 V vs. RHE. The GOR mechanism and pathway are systematically elucidated via…
