Climate change, caused by heavy CO2 emissions, is driving new demands to alleviate the rising concentration of atmospheric CO2 levels. Enlightened by the photosynthesis of green plants, photo(electro)chemical catalysis of CO2 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 CO2 reduction is widely recognized to possess high efficiencies and potentials for practical application. The efficient and selective electroreduction of CO2 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 CO2 reduction. In order to achieve high selectivity for CO2 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 CO2 electrochemical reduction of metallic catalysts are summarized. The challenges and perspectives in this field are also discussed. Different approaches for tuning the selectivity of CO2 electrochemical reduction on metallic catalysts are summarized, including the studies in electrolytes, crystal facets, oxide-derived catalysts, electronic and geometric structures, nanostructures, and mesoscale phenomena. The challenges and perspectives for future practical CO2 electroreduction and utilization in this field are also discussed.
