Harnessing Electrocatalytic Coupling of Carbon Dioxide and Methanol for High-Efficiency Formic Acid Production.

ABSTRACT: The coupling of electrocatalytic CO₂ reduction (ECR) and methanol oxidation reaction (MOR) presents a promising strategy for simultaneous cogeneration of formic acid (FA) at both cathode and anode. However, sluggish kinetics, low selectivity and efficiency hinder practical application. Herein, we demonstrate an integrated ECR||MOR system employing CuBi cathode and NiCo anode for energy-efficient FA cogeneration. The CuBi alloy achieves high Faradaic efficiencies (FE > 90%) for FA generation over an extensive potential range (>400 mV), attributed to the accelerated formation of HCOO^* intermediates in facilitating FA production. Meanwhile, the NiCo alloy reached a remarkable FE of 97.5% for FA generation at 1.4 V versus reversible hydrogen electrode, benefiting from rap
