Pulsed potential electrochemical CO 2 ... -

01/12/2020· The electrochemical conversion of CO 2 is a promising route to fuels and feedstocks. One of the great challenges in employing copper-based electrodes towards the electrocatalytic reduction of CO 2 is the unsustainable production of hydrocarbons over time. In this study, we show that by introducing a periodic pulsed operational mode during controlled potential electrolysis using low pulse ...

High-Selectivity Electrochemical Conversion of CO 2 to ...

28/09/2016· CO will result from desorption of CO ads at this stage, or alternatively, further electron transfer to these surface-adsorbed species will lead to CH 4. 1b, 13b CO 2 reduction results on the two controls, bare CNS and Cu nanoparticles on glassy carbon, indicate that both Cu metal and CNS are active for electrochemical CO 2 reduction. On the Cu surface, stronger adsorption of CO exists than ...

30/07/2019· CO 2 diffusion coefficient (D CO2) and CO 2 concentrations c CO2 are taken from literature. 57-60 Due to the porosity and tortuosity of the agglomerate, the CO 2 diffusion coefficient is reduced by the factor of 10, which can be done as a rough estimation. 54. With a current density at which HER starts to increase of 400 mA cm −2 determined at 50 °C (see Figure 8) the radius of the flooded ...

Carbon monoxide - Wikipedia

Carbon monoxide (chemical formula CO) is a colorless, odorless, tasteless, flammable gas that is slightly less dense than air. Carbon monoxide consists of one carbon atom and one oxygen atom. It is the simplest molecule of the oxocarbon family. In coordination complexes the carbon monoxide ligand is called carbonyl. Thermal combustion is the most common source of carbon monoxide, however there ...

Electrochemical reduction of carbon dioxide - Wikipedia

Electrochemical reduction of carbon dioxide represents a possible means of producing chemicals or fuels, converting carbon dioxide ( CO. 2) to organic feedstocks such as formic acid (HCOOH), carbon monoxide (CO), methane (CH 4), ethylene (C 2 H 4) and ethanol (C 2 H 5 OH). Among the more selective metallic catalysts in this field are tin for ...
