Electrochemical CO₂ reduction (CO₂R) to value-added fuels has been actively pursued to reduce the carbon intensity of our energy and products-driven economy. Conventional CO₂R is always coupled with the anodic oxygen evolution reaction (OER), resulting in high electricity input being consumed by the OER due to its large energy barrier and sluggish kinetics. Herein, OER is replaced with selective methanol oxidation reaction (MOR) on non-noble electrocatalysts. In an integrated cell, CO₂R is conducted on the cathode of Bi nanoparticles and MOR is performed on the anode of Ni(OH)₂ in alkaline electrolyte. Over 92% selectivity for cathodic reduction of CO₂ into formate and 100% selectivity for anodic oxidation of methanol to formate are achieved at high current densities within a wide potential range. The use of the integrated system significantly lowers the specific energy consumption by 57.3% reduction …
