Influence of nanoflower FeTiO3 in carbon dioxide reduction

Abstract

The effect of electrochemical reduction of carbon dioxide (CO2) by changing the structure and morphology of FeTiO3 nanoparticle prepared through sol–gel and hydrothermal methods is explained in this study. FeTiO3 nanoparticles were used as a cathode where as a stainless steel plate and CO2− saturated NaHCO3 were used as an anode and an electrolyte, respectively. The cyclic voltammetry and linear sweep voltammetry analysis were carried out comprehensively on FeTiO3-SG-and FeTiO3-HT-coated electrodes to decouple the electrochemical reduction processes of CO2 in aqueous solution. The charge transfer resistance and the product gases were studied using electrochemical impedance spectroscopy and gas chromatography, respectively. The observed results were analyzed in light of structure/morphology, particle size, and surface area of FeTiO3 nanoparticles and their influence on the effective cathodic behavior in CO2 to CO reduction.
