From RRDE to GDE: Loading-Dependent H 2 O 2 Selectivity Loss in Sn-and Sb-N-C Catalysts

Key Points

• This research investigates how catalyst loading affects the selectivity of H2O2 synthesis using Sn and Sb catalysts.
• Used single-site Sn and Sb catalysts in electrochemical synthesis
• Analyzed the selectivity of H2O2 production with varying catalyst loadings
• Employed RRDE (Rotating Ring-Disk Electrode) method for measurements
• Increased catalyst loading led to a significant selectivity loss for H2O2 synthesis.
• Selectivity decreased from X% at low loading to Y% at high loading (exact numbers not provided).
• Validates the necessity for optimizing catalyst loading in advancing oxidation processes.
