CO2 Reduction on Copper‐Nitrogen‐Doped Carbon Catalysts Tuned by Pulsed Potential Electrolysis: Effect of Pulse Potential

open access: yesAdvanced Functional Materials, EarlyView.
This study demonstrates that pulsed potential electrolysis significantly improves CO2 reduction performance on copper‐nitrogen doped carbon electrodes. The formation of cationic copper sites and metallic clusters as a function of applied intermittent potential leads to notable selectivity changes compared to potentiostatic reduction.

Defect Engineering on Commercial Carbon for Economical H2O2 Electrosynthesis Under Industrial‐Relevant Conditions

open access: yesAdvanced Functional Materials, EarlyView.
The implementation of electrocatalysts toward H2O2 electrosynthesis on an industrial scale necessitates the reconsideration of design criteria. The proposed “active sites saturation” theory shows that materials with mixed active sites normally exhibit low selectivity under practical conditions.
