dc.description.abstract | Carbon monoxide is an industrially significant chemical because it is an essential precursor for the Fisher-Tropsch process. However, solid fuels such as coal yield syngas with H-2 :CO ratio of similar to 0.7, which is unideal for hydrocarbon chain growth. Herein, we present electrochemical CO2 reduction to adjustable H-2/CO syngas ratio by controlling the thickness of silver nanostructure. By looking into the local species generated during the electrolysis using the in-situ ATR-FTIR, the increased amount of anions such as OH- and CO32- trapped within the porous structure, which increases with the thickness of the nanostructure, leads to an increase in local pH near the electrode surface, and thus at the expense of the HER, the CO production is promoted. As a result, syngas composition can be adjusted simply by controlling the thickness of the nanostructure. (C) 2021 Elsevier Ltd. All rights reserved. | - |
