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.

Implication

Reveals loading impacts H2O2 selectivity in single-site Sn and Sb catalysts, suggesting optimization needs.

Abstract

Electrochemical H 2 O 2 synthesis offers a sustainable route to advanced oxidation processes. Using single-site Sn and Sb catalysts, we reveal a strong effect of catalyst loading: the RRDE selectivity is lost...
