CO 2 reduction on doped-ceria electrodes: controlling CO selectivity and coking with applied bias
Abstract
On doped ceria, operando studies decouple electrochemical CO from rWGS. Ce 3+ sites promote CO formation. Bias controls CO yield in the overall syngas composition via creation of Ce 3+ sites. But excessive Ce 3+ promotes CO-mediated coking in PDC/GDC.
