The gradually increased concentration of carbon dioxide (CO ) in the atmosphere has been recognized as the primary culprit for the rise of the global mean temperature. In recent years, development of routes for highly efficient conversion of CO has received much attention. This Review describes recent progress on the design and synthesis of solid-state catalysts for the electrochemical reduction of CO . The significance of this catalytic conversion is presented, followed by the general parameters for CO electroreduction and a summary of the reaction apparatus. We also discuss various types of solid catalysts based on their CO conversion mechanisms. We summarize the crucial factors (particle size, surface structure, composition, etc.) determining the performance for electroreduction.

“…They permit current densities of almost two orders of magnitude higher at the same overpotential compared with planar electrodes (Weng et al., 2018) by introducing gaseous CO 2 into the electrolyte at the active site through a gas diffusion layer inside the GDE. Alternatively, the mass transport of CO 2 can be improved by increasing its solubility by adjusting the pressure (in MeOH, 333 mA·cm 2 , FE (CO) > 85%, 40 atm at Cu wire, Saeki et al., 1995a, Saeki et al., 1995b, up to 68 atm, Li and Prentice, 1997) and the temperature (down to −30°C, in MeOH, Naitoh et al., 1993, Mizuno et al., 1995, Kaneco et al., 1998a, Kaneco et al., 1998b, Kaneco et al., 1998c, Oh et al., 2014). Owing to requirements regarding the current density for an industrial application, the continuous supply of CO 2 applying GDEs is preferred over submerged electrodes.…”

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.

Vulcan XC-72R-supported Fe catalysts have been synthesised for the electroreduction of CO 2 to high-added value products. Catalysts were obtained by the polyol method, using ethylene glycol as solvent and reducing agent. Prior to the metal deposition, Vulcan was subjected to different oxidation treatments in order to modify its surface chemistry and study its influence on the physicochemical and electrochemical properties of the catalysts, as well as on the product distribution. The oxidation treatments of the supports modify their textural properties, but do not affect significantly the physicochemical properties of catalysts. However, DEMS studies showed that the carbon support degradation, the distribution of products, and the catalytic activity toward the CO 2 electroreduction reaction depend significantly on the surface chemistry of the carbon support.
