Studies on the faradaic efficiency for electrochemical reduction of carbon dioxide to formate on tin electrode

Mass Transport Effects on Electroreduction of Carbon Dioxide into Formic Acid

“…The reduction curve at circa -0.1 V vs SHE is due to part of the reducing into [5]. This is beneficial to the process as play a bigger role than in the reduction of 2 .…”

“…In the backward pass, there exist a positive current circa -0.1 V vs SHE. The current is the stripping region where is oxidised to and into 2+ [5].…”

Achieving Both High Selectivity and Current Density for CO2 Reduction to Formate on Nanoporous Tin Foam Electrocatalysts

“…Lv et al studied the catalytic properties of commercial tin foil for the electroreduction of CO2 to formate. [10] The optimal conditions were 0.1 M KHCO3 at -1.8 V vs. Ag/AgCl, under which the Faradaic efficiency was up to 91% however, the current density was only 2.5 mA cm -2 . Zhang et al prepared high surface area tin oxide nanocrystals by a facile hydrothermal method and investigated its capability for CO2 reduction to formate in 0.1 M NaHCO3 solution.…”

Large-scale cathodic carboxylation of copper surfaces

“…Carbon dioxide is known to react under a wide range of cathodic processes and many papers have recently been published on its catalytic reduction at different metallic surfaces [1][2][3][4][5][6][7][8][9][10][11][12][13][14]. Contributions based on the reduction of CO 2 to methanol, carbon monoxide, methane or salts such as oxalates might appear as a partial solution to decreasing the environmental nuisance of this effluent.…”
