Toward Efficient Tandem Electroreduction of CO2 to Methanol using Anodised Titanium
(ACS, 2021-06-28)
The electroreduction of CO2 (CO2RR) using renewable electricity is an appealing route to synthesize methanol (CH3OH), a valuable C1 feedstock and fuel. Unfortunately, there are still no workhorse electrocatalysts with ...
Selectivity Map for the Late Stages of CO and CO2 Reduction to C2 Species on Cu Electrodes
(Wiley, 2021-02-01)
The electrochemical CO and CO2 reduction reactions (CORR and CO2RR) using copper catalysts and renewable electricity hold promise as a carbon-neutral route to produce commodity chemicals and fuels. However, the exact ...
How symmetry factors cause potential- and facet-dependent pathway shifts during CO2 reduction to CH4 on Cu electrodes
(Elsevier, 2020-12-28)
The deactivation of copper electrodes is a serious problem that can affect the scalability and deployment of CO2 electrolyzers. The effect is generally attributed to the cathodic deposition of Fe and Zn impurities from the ...
Enhancing CO2 Electroreduction to Ethanol on Copper-Silver Composites by Opening an Alternative Catalytic Pathway
(ACS, 2020-03-16)
A fundamental question in the electrochemical CO2 reduction reaction (CO2RR) is how to rationally control the catalytic selectivity. For instance, adding a CO-producing metal like Ag to Cu shifts the latter’s CO2RR selectivity ...
Enhanced Charge Transfer Kinetics for the Electroreduction of Carbon Dioxide on Silver Electrodes Functionalized with Cationic Surfactants
(Wiley, 2022-12-09)
Cationic ammonium surfactants can be used together with a suitable catalyst to enhance the electroreduction of carbon dioxide (CO2RR). However, the underlying reasons for the improvements are not yet well understood. In ...
