Electrochemically reducing CO2 using renewable energy is a contemporary global challenge that will only be met with electrocatalysts capable of efficiently converting CO2 into fuels and chemicals with high selectivity. Although many different metals and morphologies have been tested for CO2 electrocatalysis over the last several decades, relatively limited attention has been committed to the study of alloys for this application. Alloying is a promising method to tailor the geometric and electric environments of active sites. The parameter space for discovering new alloys for CO2 electrocatalysis is particularly large because of the myriad products that can be formed during CO2 reduction. In this Minireview, mixed‐metal electrocatalyst compositions that have been evaluated for CO2 reduction are summarized. A distillation of the structure–property relationships gleaned from this survey are intended to help in the construction of guidelines for discovering new classes of alloys for the CO2 reduction reaction.

“…Therefore, these AuCu bimetallic nanoparticles are capable of providing active site to further stabilize *COOH, leading to a preference of CO formation. In (1− x ) M x (M = Fe, CO, Ni, Cu, Zn) alloys were also studied as electrocatalysts for CO production via reducing CO 2 . By combing In metal, which weakly binds with H and CO, with late 3d transition metals possessing a strong MCO binding energy may suppress hydrogen evolution and improve the formation of CO.…”

Climate change, caused by heavy CO emissions, is driving new demands to alleviate the rising concentration of atmospheric CO levels. Enlightened by the photosynthesis of green plants, photo(electro)chemical catalysis of CO reduction, also known as artificial photosynthesis, is emerged as a promising candidate to address these demands and is widely investigated during the past decade. Among various artificial photosynthetic systems, solar-driven electrochemical CO reduction is widely recognized to possess high efficiencies and potentials for practical application. The efficient and selective electroreduction of CO is the key to the overall solar-to-chemical efficiency of artificial photosynthesis. Recent studies show that various metallic materials possess the capability to play as electrocatalysts for CO reduction. In order to achieve high selectivity for CO reduction products, various efforts are made including studies on electrolytes, crystal facets, oxide-derived catalysts, electronic and geometric structures, nanostructures, and mesoscale phenomena. In this Review, these methods for tuning the selectivity of CO electrochemical reduction of metallic catalysts are summarized. The challenges and perspectives in this field are also discussed.

“…Moreover, the hydrogen evolution reaction (HER) occurs at a very similar potential range to CO 2 RR, which leads to a low selectivity of CO 2 RR. To overcome the drawbacks mentioned above, a series of electrocatalysts including nanostructured metals, alloys, oxides, and chalcogenides have been explored to catalyze the conversion of CO 2 to CO, HCOOH, CH 3 OH, and others . Among them, carbon‐based functional materials have unique advantages for electrocatalysis owing to their tunable molecular structures, high electrical conductivity, and strong acidic/alkaline resistance .…”

Metal‐N‐C is a type of attractive electrocatalyst for efficient CO2 reduction to CO. Because of the ambiguity in their atomic structures, the active sites and catalytic mechanisms of the catalysts have remained under debate. Here, the effects of N and C hybrid coordination on the activity of Ni‐N‐C catalysts were investigated, combining theoretical and experimental methods. The theoretical calculations revealed that N and C hybrid coordination greatly enhanced the capability of single‐atom Ni active sites to provide electrons to reactant molecules and strengthens the bonding of Ni to N and C in the Ni‐N‐C complexes. During the reaction process, the C and N coordination synergistically optimized the reaction energies in the conversion of CO2 to CO. A good agreement between theoretical calculations and electrochemical experiments was achieved based on the newly developed Ni‐N‐C electrocatalysts. The activity of hybrid‐coordination NiN2C2 was more than double that of single‐coordination NiN4.
