Monitoring Active Sites for Hydrogen Evolution Reaction at Model Carbon Surfaces
(RSC, 2021-03-25)Carbon is ubiquitous as an electrode material in electrochemical energy conversion devices. If used as support material, the evolution of H2 is undesired on carbon. However, recently carbon-based materials are of high ... -
Structure-sensitive scaling relations among carbon-containing species and their possible impact on CO2 electroreduction
(Elsevier, 2021-01-24)The arduous modelling of reactions at heterogeneous catalysts is greatly simplified when adsorption-energy scaling relations between intermediates exist. The offset of these linear relations is structure-independent when ... -
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 ...
