“…In all other cases, the H 2 -evolution is promoted. In fact, comparable behaviours had also been observed during the CO 2 reduction in our previous studies on conducting polymer electrodes [19][20][21][22][23]. The results obtained on Pb granule electrodes in the fixed-bed reactor at different high-pressure values are presented in Table 1.…”

“…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.…”

“…The mechanism of formic acid, formaldehyde, and methanol production was presented by Brito et al [188]. It is already known that formic acid is the first product formed; however, it is easily reduced to formaldehyde and methanol [190,207]. Table 5 shows the main products generated and the percentage of conversion efficiency obtained from photoelectrocatalytic CO 2 reduction in different semiconductors.…”

The great versatility of semiconductor materials and the possibility of generation of electrons, holes, hydroxyl radicals, and/or superoxide radicals have increased the applicability of photoelectrocatalysis dramatically in the contemporary world. Photoelectrocatalysis takes advantage of the heterogeneous photocatalytic process by applying a biased potential on a photoelectrode in which the catalyst is supported. This configuration allows more effectiveness of the separation of photogenerated charges due to light irradiation with energy being higher compared to that of the band gap energy of the semiconductor, which thereby leads to an increase in the lifetime of the electron-hole pairs. This work presents a compiled and critical review of photoelectrocatalysis, trends and future prospects of the technique applied in environmental protection studies, hydrogen generation, and water disinfection. Special attention will be focused on the applications of TiO 2 and the production of nanometric morphologies with a great improvement in the photocatalyst properties useful for the degradation of organic pollutants, the reduction of inorganic contaminants, the conversion of CO 2 , microorganism inactivation, and water splitting for hydrogen generation.

“…The synthesis of hydrocarbons on Cu electrodes is a complex multistep reaction with adsorbed intermediates, and most notably adsorbed CO. This reaction product distribution is very sensitive to various parameters such as applied potential, buffer strength and local pH, local CO 2 concentration, CO 2 pressure and the surface crystal structure of the electrode [5,8,[14][15][16][17][18][19][20][21][22][23][24]. Elsewhere, on several transition metal electrodes (Ni, Pd, Pt…) carbon monoxide was mainly formed [25][26][27][28][29][30][31].…”

Electro-reduction of carbon dioxide to formate on lead electrode in aqueous medium

The electrochemical reduction of carbon dioxide on a lead electrode was studied in aqueous medium. Preliminary investigations carried out by cyclic voltammetry were used to determine the optimized conditions of electrolysis. They revealed that the CO 2 reduction process was enhanced at a pH value of 8.6 for the cathodic solution i.e. when the predominant form of CO 2 was hydrogenocarbonate ion. Long-term electrolysis was carried out using both potentiometry and amperometry methods in a filterpress cell in which the two compartments were separated by a cation-exchange membrane (Nafion Ò 423). Formate was detected and quantified by chromatography as the exclusive organic compound produced with a high Faradaic yield (from 65% to 90%). This study also revealed that the operating temperature played a key role in the hydrogenation reaction of carbon dioxide into formate in aqueous medium.
