Abstract

The foremost aim for performing this study was to focus on the electrodeposition of mixed hydrogen molybdenum tungsten bronze films, which have the potential for e transfer interactions carrying out the reduction of carbon dioxide. A yellow peroxymolybdic tungstate solution was prepared and used for the electrodeposition of hydrogen molybdenum tungsten bronze films on conductive carbon paper. Electrodeposition was carried out at -2.0 V from 20 - 120 minutes to determine the effect of deposition time on film thickness and CO2 reduction. These films were characterized by X-ray photoelectron spectroscopy. The deposited films served as a working electrode for CO2 electrochemical reduction utilizing 0.8 M NaHCO3 as the electrolyte. Carbon dioxide gas was bubbled into the cathode solution for an hour while bulk electrolysis was carried out at different applied potentials. Products were identified and evaluated using ion chromatography.
