Electrochemical Reduction of CO₂ to Formate on Easily Prepared Carbon-Supported Bi Nanoparticles.

ABSTRACT: Herein, the electrochemical reduction of CO₂ to formate on carbon-supported bismuth nanoparticles is reported. Carbon-supported Bi nanoparticles (about 10 nm in size) were synthesized using a simple, fast and scalable approach performed under room conditions. The so-prepared Bi electrocatalyst was characterized by different physicochemical techniques, including transmission electron microscopy, X-ray photoelectron spectroscopy, and X-ray diffraction and subsequently air-brushed on a carbon paper to prepare electrodes. These electrodes were characterized by scanning electron microscopy, energy-dispersive X-ray spectroscopy and also by cyclic voltammetry. Finally, CO₂ electroreduction electrolyses were performed at different electrode potentials for 3 h. At the optimal
