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.
