Critical role of hydrogen sorption kinetics in electrocatalytic CO2 reduction revealed by on-chip in situ transport investigations

Abstract

Electrochemical hydrogen-participating processes are commonly relevant in multiple clean energy technologies. Here, authors achieve in situ quantification of H sorption kinetics during Pd-catalyzed CO2 reduction, unravelling its key role within the interfacial network of local pH, proton donors and CO2 molecules.
