DOI: 10.1017/s1431927617011199
Abstract: During a catalytic process, a catalyst may undergo changes of its structure or morphology, as well as modifications of its local composition, which is due to oxidation/reduction processes, surface segregation, or even the presence of… read more here.

DOI: 10.1021/acs.jpcc.7b08278
Abstract: Oxide-derived copper (OD-Cu) electrodes exhibit higher activity than pristine copper during the carbon dioxide reduction reaction (CO2RR) and higher selectivity toward ethylene. The presence of residual subsurface oxygen in OD-Cu has been proposed to be… read more here.

DOI: 10.1021/acs.jpcc.8b04983
Abstract: Under ambient conditions, copper with oxygen near the surface displays strengthened CO2 and CO adsorption energies. This finding is often used to rationalize differences seen in product distributions between Cu-oxide and pure Cu electrodes during… read more here.
