Electrochemical reduction of carbonate solutions at low temperatures

CdS nanoparticles deposited on montmorillonite: Preparation, characterization and application for photoreduction of carbon dioxide

“…There is some controversy about the reduction of HCO À 3 [45]. For example, Hori [46] found hydrogen carbonate to be an electroinactive compound that can be decomposed to CO 2 …”

Reduction of CO2 under high pressure and high temperature on Pb-granule electrodes in a fixed-bed reactor in aqueous medium

“…For the reduction of CO 2 , most of the metals in the periodic table of the elements [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18] and synthetic metals (conducting polymers) such as polyaniline and polypyrrole [19][20][21][22][23][24] have been used as electrode material in different electrolytes and in various electrochemical cells. Most of the cited works here have been done in H-cells with metal plate electrodes.…”

Decisive Intermediates Responsible for the Carbonaceous Products of CO2 Electro‐reduction on Nitrogen‐Doped sp2 Nanocarbon Catalysts in NaHCO3 Aqueous Electrolyte

“…Despite that the dissolved CO 2 was generally regarded as the dominant carbon source for electro‐reduction, the possibility of the direct reduction of HCO 3 − species was still in dispute and this matter had been commonly ignored. Previous studies have reported CH 4 , C 2 H 4 , HCHO, CH 3 OH and other carbonaceous products on Cu and Pt electrodes in a bicarbonate electrolyte in the absence of CO 2 , and HCO 2 − could be produced from HCO 3 − on Pd impregnated polymer electrodes or metallic Pd electrodes . Furthermore, a recent spectroscopy study by Innocent et al.…”
