“…By alloying, the binding strength of intermediates on a catalyst surface can be tuned by varying the composition and ratio of metal elements [89][90][91]. For example, Kim et al synthesized Au-Cu bimetallic nanoparticle alloys with different Au/Cu ratios and found that Au 3 Cu nanoparticle monolayers had the highest mass activity for CO production, outperforming conventional CO 2 reduction catalysts [20].…”

a b s t r a c tElectrochemical reduction of carbon dioxide powered by renewable electricity represents a promising solution for energy and environmental sustainability. To enable this technology, active and selective catalysts must be developed. Noble metals exhibit excellent activity but are hampered by their low abundance and high cost. Thus, searching for efficient nonprecious metal catalysts for practical applications is vital. In this review, the recent progress on nanostructured nonprecious metal catalysts for electrochemical reduction of carbon dioxide is summarized. These catalysts are classified into five categories: metals, partially oxidized metals, metal oxides and sulfides, doped carbons, and organic frameworks. The areas of focus are material synthesis, structure and components, catalytic performance, and reaction mechanisms. Several important factors that affect activity, such as particle size, interface strain, grain boundary, crystal facet, oxidation state, heteroatom configuration, and organic hybrid, are discussed. Finally, some perspectives are provided for future developments and directions of the synthesis and functionalization of nonprecious metal catalysts, with emphasis on the potential advantages of nanoporous materials for carbon dioxide reduction.

“…Compared with pure Au, Au 3 Cu nanoparticles yielded more hydrocarbons and hydrogen with less CO production in a 0.1 M KH 2 PO 4 +0.1 M K 2 HPO 4 buffered solution [55,56]. Bulk Au is a CO production catalyst, as CO can easily desorb from the surface due to its weak binding strength.…”

Carbon dioxide electrochemical reduction has attracted significant attention due to its great potential in environmental protection and energy storage. In this mini-review, some recent progress in heterogeneous electrochemical reduction of carbon dioxide is summarized, with a particular emphasis on the effects of catalyst surface modification. Several structural (metal overlayers, particle size adjustment, roughness creation, special 2D or 3D structure patterning) and compositional (alloy, doping, oxide, and composite) modification techniques are reviewed and discussed. Research directions towards more advanced catalysts design are proposed.
