Solvents and Supporting Electrolytes in the Electrocatalytic Reduction of CO2

Different electrolytes applied in the aqueous electrocatalytic CO 2 reduction reaction (CO 2 RR) considerably influence the catalyst performance. Their concentration, species, buffer capacity, and pH value influence the local reaction conditions and impact the product distribution of the electrocatalyst. Relevant properties of prospective solvents include their basicity, CO 2 solubility, conductivity, and toxicity, which affect the CO 2 RR and the applicability of the solvents. The complexity of an electrochemical system impedes the direct correlation between a single parameter and cell performance indicators such as the Faradaic efficiency; thus the effects of different electrolytes are often not fully comprehended. For an industrial application, a deeper understanding of the effects described in this review can help with the prediction of performance, as well as the development of scalable electrolyzers. In this review, the application of supporting electrolytes and different solvents in the CO 2 RR reported in the literature are summarized and discussed.

“…The second category is organic electrolytes like small molecular organic solvents with large polarity, such as methanol, acetonitrile, and N,N-dimethylformamide, which could be mixed with some alkali salts to meet the high conductivity requirement. [239][240][241][242][243][244][245][246][247] However, due to the poor conductivity of organic electrolytes and poor stability of the diaphragm in organic electrolytes, organic electrolytes have not been frequently used recently. The third category is ionic liquids (also known as room temperature molten salts), which are typically composed of large cations (e.g., imidazolium, quaternary ammonium, and pyridinium) and small anions (e.g., AlC1 ).…”

Electrochemical carbon dioxide reduction reaction (CO2RR) offers a promising way of effectively converting CO2 to value‐added chemicals and fuels by utilizing renewable electricity. To date, the electrochemical reduction of CO2 to single‐carbon products, especially carbon monoxide and formate, has been well achieved. However, the efficient conversion of CO2 to more valuable multicarbon products (e.g., ethylene, ethanol, n‐propanol, and n‐butanol) is difficult and still under intense investigation. Here, recent progresses in the electrochemical CO2 reduction to multicarbon products using copper‐based catalysts are reviewed. First, the mechanism of CO2RR is briefly described. Then, representative approaches of catalyst engineering are introduced toward the formation of multicarbon products in CO2RR, such as composition, morphology, crystal phase, facet, defect, strain, and surface and interface. Subsequently, key aspects of cell engineering for CO2RR, including electrode, electrolyte, and cell design, are also discussed. Finally, recent advances are summarized and some personal perspectives in this research direction are provided.

“…In addition, CO 2 has a high solubility in organic solutions. Among them, the most studied are ionic liquids [19][20][21][22][23][24][25][26], methanol solutions [27][28][29], and organic aprotic solvents [30][31][32][33][34][35][36][37][38][39][40]. In recent years, there has also been engagement in the CO 2 electrochemical reduction process in molten salts [41][42][43][44][45][46].…”

An annual increase of CO2 concentrations in the atmosphere causes global environmental problems, addressed by systematic research to develop effective technologies for capturing and utilizing carbon dioxide. Electrochemical catalytic reduction is one of the effective directions of CO2 conversion into valuable chemicals and fuels. The electrochemical conversion of CO2 at catalytically active electrodes in aqueous solutions is the most studied. However, the problems of low selectivity for target products and hydrogen evolution are unresolved. Literature sources on CO2 reduction at catalytically active cathodes in nonaqueous mediums, particularly in organic aprotic solvents, are analyzed in this article. Two directions of cathodic reduction of CO2 are considered—nonaqueous organic aprotic solvents and organic aprotic solvents containing water. The current interpretation of the cathodic conversion mechanism of carbon (IV) oxide into CO and organic products and the main factors influencing the rate of CO2 reduction, Faradaic efficiency of conversion products, and the ratio of direct cathodic reduction of CO2 are given. The influence of the nature of organic aprotic solvent is analyzed, including the topography of the catalytically active cathode, values of cathode potential, and temperature. Emphasis is placed on the role of water impurities in reducing CO2 electroreduction overpotentials and the formation of new CO2 conversion products, including formate and H2.
