Electrochemical Reduction of CO2 by the SnS| PTFE| Pt Surface in an Aqueous Imidazole Medium: Catalysis and Kinetics

“…The metallic surface offers a way of activating this inert molecule for reduction reaction by adsorbing CO 2 on its surface and forming a partially negative species (CO 2 δ·– ) through interaction with surface atoms . Subsequently, the negative intermediate species undergoes further reduction to generate a stable product, the composition of which is dependent upon various factors including reaction conditions, electrolytes, and notably, the electrode materials employed. , Particularly, the conversion of CO 2 to nontoxic liquid like formate is highly desirable owing to its large market value. Formate compounds can further be subjected to application in direct fuel cells as hydrogen carrier systems .…”
