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 (NiSA) Co (CoSA) dual sites anchored on nitrogen-doped carbon nanotubes embedded with Ni0.1Co0.9 alloy (Ni0.1Co0.9@NiSACoSA-NCNTs) are constructed for electrochemical GOR. Remarkably, it can reach 10 mA cm-2 at a low 1.15 V versus the reversible hydrogen electrode (vs. RHE) realize formate selectivity 93.27 % even conversion 98.81 1.45 vs. RHE. The GOR mechanism pathway systematically elucidated via experimental analyses theoretical calculations. It revealed that hydroxyl (*OH) be produced during NiSA, CoSA, synergistically optimizes electronic structure CoSA sites, reducing energy barriers *OH-mediated bonds dehydrogenation C1 intermediates. This decreases number intermediates steps GOR-to-FA, thus increasing production efficiency. After coupling evolution in membrane assembly cell, 14.26 g 23.10 L H2 100 108 h.

Abstract Electrocatalytic oxidation of glycerol, an oversupplied byproduct the biodiesel industry, into high‐valued chemicals is alluring to diminishing current dependence on fossil energy. Formic acid important glycerol product that serves as a high‐energy‐density fuel and crucial precursor for fine chemical industry while developing electrocatalyst efficiently convert formic remains challenge. Herein, Cu‐doped nickel phosphide (Cu x Ni 2– P) electrocatalyst, achieving formate productivity ≈11 mol m −2 h −1 at 1.54 V versus RHE over broad concentration range (10–100 ) reported, which greater than threefolds 2 P. Furthermore, Cu P can enhance cleavage C─C bond in reducing production intermediates thus attaining high selectivity formate. In situ experiments integrated with density functional theory (DFT) calculation revealed doping promote generation III ─OOH species enrich substrates local environments surface, facilitating reaction efficiency. Finally, study designed membrane‐free flow electrolyzer continuous upgrading formate, 16.4 mmol coupled 0.68 L H 1.75 8 h.
