Electrolyte Effects on Electrochemical CO₂ Reduction Reaction at Sn Metallic Electrode.

ABSTRACT: Understanding the electrolyte factors governing the electrochemical CO₂ reduction reaction (CO₂RR) is fundamental for selecting the optimized electrolyte conditions for practical applications. While noble metals are frequently studied, the electrolyte effects on the CO₂RR on Sn catalysts are not well explored. Here, we studied the electrolyte effect on Sn metallic electrodes, investigating the impact of electrolyte concentration, cation identity, and anion properties, and how it shapes the CO₂RR activity and selectivity. The activity for formic acid and carbon monoxide increases with the cation concentration and size at mild acid conditions. In contrast, hydrogen production is not strongly influenced by the cathodic potential, electrolyte concent
