“…In general, the products from CO 2 RR can be divided into two categories: 1) C 1 products such as CO, [ 3,4 ] methanol, [ 5,6 ] formate (or formic acid), [ 7,8 ] etc. ; 2) multi‐carbon (C 2+ ) products including ethylene, [ 9,10 ] ethanol, [ 11 ] etc. Lately, techno‐economic estimation elucidates that the generation of formate (or formic acid) or carbon oxide is much cost‐effective in comparison with other products.…”

Electrochemical reduction of CO2 to high‐value chemical feedstocks, such as formate, is one of the most promising ways to alleviate the greenhouse effect. Unfortunately, the exploration of electrocatalysts with high activity and selectivity over a wide potential window (especially low potential for high current density) still remains a grand challenge. In this study, the fabrication of bismuthene nanosheets using an in‐situ electrochemical transformation strategy of monoclinic scheelite BiVO4 flakes is demonstrated. Catalyzing the CO2 electroreduction in 1 m KHCO3 aqueous solution, the bismuthene nanosheets exhibit a dramatically high formate Faradaic efficiency (FE) of ≈97.4% and a very large current density of −105.4 mA cm−2 at −1.0 V versus reversible hydrogen electrode. Significantly, over a record wide potential window of 750 mV from the initial −0.65 V to the applied minimum −1.4 V, the formate FEs of the bismuthene nanosheets are always higher than 90%, outperforming state‐of‐the‐art electrocatalysts. Both experimental and theoretical investigations reveal that, in comparison with •COOH and H• intermediates, the bismuthene nanosheets preferentially promote fast reaction kinetics towards HCOO•, which eventually accelerates the production of formate.

“…[ 58,59 ] In simple terms, loading a metal nanoparticle on a support not only changes the interface coordination environment, lattice strain, number of active sites, and other chemical and physical parameters, but also the changes of these intrinsic parameters significantly regulate their electronic structure and chemical properties. [ 60–62 ] Therefore, a major factor in changing the performance of NPCs is the selection of the most suitable supported material. For example, Park et al.…”

Electrocatalysis is viewed as one of the most effective ways to mitigate the energy problems and produce fuels or value‐added chemicals in a gentle manner. However, duo to the limited electrochemical properties of various systems, there is an intensive search for highly efficient electrocatalysts by more rational control over the topographic structure, chemical structure, and electronic structure. At present, the development of electrocatalysts mainly includes two directions: (1) nanoparticle electrocatalysts, and (2) single atom site electrocatalysts (SACs). Nanoparticle and SACs display their own advantages, and have been widely studied in the field of electrocatalysis. Considering the state‐of‐the‐art progress for nanoparticles or SACs, the selection of effective electrocatalysts has been a topic of great research value. Therefore, this paper summarizes the advantages, commonalities, and problems of nanoparticle and SACs, as well as their developing methods and experiences. In addition, the selection of nanoparticle and SACs in electrocatalytic reactions was discussed from the aspects of their respective influencing factors, active sites and synergistic effect. Finally, the research of nanoparticle and single atom sites electrocatalysts were prospected, providing a general guidance for the selection of efficient electrocatalysts.

“…Therefore, some strategy to improve the performance of CO 2 RR have been developed. Recently, Gong group reported a controllable grain growth of copper electrodeposition using poly(vinylpyrrolidone) as an additive [71] . The existence of grain boundaries enhances the adsorption of the key intermediate (*CO) on the copper surface to boost further reduction.…”

Converting carbon dioxide (CO2) into high‐value fuels or chemicals is considered as a promising way to utilize CO2 and alleviate the excessive greenhouse gas emission. Among multiple catalysis approaches, electrochemical reduction of CO2 to ethanol has an important prospect due to the high energy density and widely applications of ethanol. In recent years, many electrocatalysts for CO2 reduce reaction (CO2RR) have shown promising catalytic activity for ethanol production. In this review, we will introduce the recent progress in this field. The basic principles and electrochemical performances of CO2RR are reviewed at first. Then, several categories of active electrocatalysts for CO2RR to ethanol are summarized, including the discussion of reaction mechanism and catalytic sites. Finally, several possible strategies are proposed, providing guidance for future design and preparation of high‐performance catalysts.
