| Abstract: | Development of a novel SnS⎸PTFE⎸Pt electrode as an efficient catalyst for electrochemical CO2 reduction to formate in aqueous alkaline imidazole medium is reported in this paper. The electrode was prepared through the incorporation of poly-tetrafluoroethylene (PTFE) with SnS and modification of Pt surface by SnS/PTFE. The electrode facilitated a first-order CO2 reduction at -1.1 V vs. Ag/AgCl (saturated KCl) via a diffusion-controlled pathway with a cathodic electron transfer coefficient ( ) of 0.22 and two-electron transfer kinetics in two steps, where the first electron transfer step determined the reaction rate. The SnS⎸PTFE⎸Pt electrode surface exhibited well-defined cyclic voltammograms (CVs) for CO2 reduction in comparison to GCE, Au, Pd, and graphite-modified electrodes utilizing the same catalyst, indicating superior catalytic efficiency and its conduciveness to kinetic investigations. Such performance indicates that the SnS⎸PTFE⎸Pt electrode would be a promising alternative for CO2 reduction in the context of renewable energy generation. |
