“…So, how to efficiently reduce the content of carbon dioxide in the atmosphere and effectively utilize it has become an important research topic [7][8][9]. Different approaches have been proposed to address the CO 2 issue, such as increasing the efficiency of fossil fuel combustion, enhancing the physical capture and storage of carbon dioxide, and enhancing the conversion of carbon dioxide to valuable chemicals [10,11]. Among these solutions, electrochemical reduction of carbon dioxide is an effective and proven technology.…”

Ni-based single-atom catalysis (Ni-SAC) has been experimentally reported with superior performance in reducing CO 2 to CO. However, due to the ambiguities in its structures, the active sites of Ni-SAC that are responsible for superior performance have not yet been resolved. This work investigates the CO 2 reduction reaction (CO 2 RR) mechanism on Ni-SAC by carrying out quantum mechanics (QM) simulation to consider both solvation effects. After exploring multiple possible combinations of N, S, and C, we distinguish a Ni-SAC site with two C, one S, and one N, representing the best performance. The predicted formation energy is closely consistent with experimental onset potential. Our prediction also suggests further improvement by finely tuning the electronics state of metal sites by changing the SAC support.

“…As a multi‐step reaction, the ethanol formation can also be achieved by a relay of multiple types of active species, in which their form of combination is critical. In our previous work, CoO‐anchored N‐doped carbon material showed high selectivity of CO 2 RR to ethanol (Figure 16d) [78] . In this composite catalyst, CoO catalyze the formation of *CO intermediates, which spill over to mesoporous carbon/carbon nanotubes for C−C coupling and form ethanol.…”

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.

[46,47] Most of these methods undergo oxidation step followed by an in-situ reduction to metallic state during ECO 2 R. In this section, the preparation of Table 2.

Converting CO2 to renewable fuels via clean and cost‐effective chemical processes is very desirable for the sustainable development of green civilization. The electrochemical CO2 reduction (ECO2R) to ethanol using renewable energy is a green and effective strategy for addressing global warming and energy shortage issues. But, simultaneous generation of multiple gaseous & liquid products and low catalytic activities are limiting the technology‘s practical use in the short term. In this study, recent scientific developments in ECO2R for selective production of ethanol are reviewed which include both theoretical and experimental aspects. The reported electro‐catalysts are categorized into different groups and the performance of these electro‐catalysts/electrodes is summarized. The effect of electro‐catalysts’ composition & its morphology, applied potential, type of electrolyte, metal loading, reactor configuration, etc. are comprehensively summarized. Furthermore, the present status & challenges and future prospects are presented to help in future design and planning of high‐performance electro‐catalysts for ethanol.
