Different promoting roles of ruthenium for the oxidation of primary and secondary alcohols on PtRu electrocatalysts
(Elsevier, 2021-06-17)
This study shows remarkably different features between the oxidation of secondary and primary C3-C5 alcohols. The oxidation of primary alcohols is controlled by the oxidative removal of blocking adsorbates, such as CO, ...
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 ...
Elucidating the Structure of Ethanol-Producing Active Sites at Oxide-Derived Cu Electrocatalysts
(ACS, 2020-08-21)
The discovery of oxide-derived copper catalysts for CO2 electroreduction is an outstanding advance in the field of electrocatalysis. Their low overpotentials and improved selectivity towards C2 products make them unique. ...
Designing water splitting catalysts using rules of thumb: advantages, dangers and alternatives
(RSC, 2020-03-09)
Thermodynamic analysis of the oxygen evolution reaction (OER) hints toward an intrinsic overpotential caused by the nonoptimal adsorption-energy scaling relation between OH and OOH. Consequently, nowadays it is a widely ...
Mechanistic insight into electrocatalytic glyoxal reduction on copper and its relation to CO2 reduction
(Royal Society of Chemistry, 2022)
Copper electrodes produce several industrially relevant chemicals and fuels during the electrochemical CO2 reduction reaction (CO2RR). Knowledge about the reaction pathways can help tune the reaction selectivity toward ...
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 ...
