Toward Standardization in CO2 Electrolysis: A Round Robin Study

Advanced Energy Materials, EarlyView.
CO2 electrolysis is a promising green technology for producing fuels and chemicals. To support its real‐world adoption, researchers conducted a collaborative study to identify sources of experimental variability. They found key differences in temperature and pressure control across labs and proposed a standardized testing protocol to improve ...

In Situ Measurement of Oxygen Vacancy Dynamics and Surface Exchange Reactions in Oxide Electrode under Solid Electrochemical Cell Operating Conditions

Advanced Energy Materials, EarlyView.
This study establishes an in situ electrochemical framework using dense bulk electrodes to identify defect chemistry and surface kinetics. While oxygen vacancy concentration is derived via bias modulation, surface exchange coefficients are quantified at open circuit voltage conditions to isolate kinetics.
