“…As calculated by DFT, these low‐coordination sites are more active for CO 2 reduction owing to lower energy barriers for the formation of key intermediates. Gonçalves et al also reported that the morphology of the Cu electrode has a great impact on the product selectivity . The major gaseous products for dendritic Cu are CO, methane, and ethylene.…”

In view of the climate changes caused by the continuously rising levels of atmospheric CO2 , advanced technologies associated with CO2 conversion are highly desirable. In recent decades, electrochemical reduction of CO2 has been extensively studied since it can reduce CO2 to value-added chemicals and fuels. Considering the sluggish reaction kinetics of the CO2 molecule, efficient and robust electrocatalysts are required to promote this conversion reaction. Here, recent progress and opportunities in inorganic heterogeneous electrocatalysts for CO2 reduction are discussed, from the viewpoint of both experimental and computational aspects. Based on elemental composition, the inorganic catalysts presented here are classified into four groups: metals, transition-metal oxides, transition-metal chalcogenides, and carbon-based materials. However, despite encouraging accomplishments made in this area, substantial advances in CO2 electrolysis are still needed to meet the criteria for practical applications. Therefore, in the last part, several promising strategies, including surface engineering, chemical modification, nanostructured catalysts, and composite materials, are proposed to facilitate the future development of CO2 electroreduction.

“…With the progress in nanofabrication technologies, complicated nanostructured Cu catalysts with 3D morphologies have been prepared for CO 2 reduction [66][67][68][69][70][71][72][73][74][75][76][77]. Zero-dimensional nanoparticles, 1D nanowires or nanorods, or 2D nanosheets are assembled into 3D hierarchical structures, which greatly increase specific areas with more exposed active sites and improve the capability of mass transfer.…”

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.

“…It has been reported by many researchers that the electroreduction of CO 2 on copper is very sensitive to its surface structure (52,54). Hori et al (52,55) described that the formation of C 2 H 4 occurs preferentially at Cu (100) facets at potentials lower than that for Cu foil, while the formation of CH 4 took place selectively at Cu (111) at the same potentials.…”

The increasing atmospheric levels of carbon dioxide (CO 2 ) must be controlled or better reverted to avoid undesirable climate changes. The electrochemical reduction of CO 2 into hydrocarbons is the best approach to solve this problem because it will recycle the 'spent' CO 2 , known as carbon neutral cycle, and will probably be able to remit the energy crises. Nanostructured copper is a novel material known for the efficient and selective reduction of CO 2 into hydrocarbons. This review attempts to summarize the recent development of enlarged surface area nanostructured copper for the efficient reduction of CO 2 into hydrocarbons using renewable energy resources at low overpotentials. The effects of different reaction conditions (e.g. applied potential, CO 2 concentration and electrode surface) on the products and some relationships between these conditions and products are discussed here. Latest achievements in the CO 2 electroreduction technology, remaining challenges and perspective research directions for practical applications are also presented. ARTICLE HISTORY
