Elucidating the Facet-dependent Selectivity for CO2 Electroreduction to Ethanol of Cu-Ag Tandem Catalysts
Iyengar, Pranit; Kolb, Manuel J.; Pankhurst, James R.; Calle Vallejo, Federico; Buonsanti, Raffaella (ACS, 2021-04-07)Despite being desirable high-value products of the electrochemical CO2 reduction reaction (CO2RR), alcohols are still obtained with lower selectivity compared to hydrocarbons and the reaction pathways leading to their ... -
Enhanced Charge Transfer Kinetics for the Electroreduction of Carbon Dioxide on Silver Electrodes Functionalized with Cationic Surfactants
Teh, Wei Jie; Kolb, Manuel J.; Calle Vallejo, Federico; Yeo, Boon Siang (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 ... -
Structure-sensitive scaling relations among carbon-containing species and their possible impact on CO2 electroreduction
Kolb, Manuel J.; Loffreda, David; Sautet, Philippe; Calle Vallejo, Federico (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 ... -
Theory-guided enhancement of CO2 reduction to ethanol on Ag-Cu tandem catalysts via particle-size effects
Iyengar, Pranit; Kolb, Manuel J.; Pankhurst, James R.; Calle Vallejo, Federico; Buonsanti, Raffaella (ACS, 2021-10-18)In the CO2 reduction reaction, the design of electrocatalysts that selectively promote alcohols over hydrocarbons (e.g., ethanol over ethylene) hinges on the understanding of the pathways and specific sites that forms ...
