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 this paper. The was prepared through the incorporation polytetrafluoroethylene (PTFE) with SnS and modification surface by SnS/PTFE. facilitated first-order at −1.1 V vs Ag/AgCl (saturated KCl) via diffusion-controlled pathway cathodic electron transfer coefficient (α) 0.22 two-electron kinetics two steps, where first step determined reaction rate. exhibited well-defined cyclic voltammograms (CVs) comparison GCE, Au, Pd, graphite-modified electrodes utilizing same catalyst, indicating superior catalytic efficiency its conduciveness kinetic investigations. Such performance indicates that would be promising alternative context renewable energy generation.
