From RRDE to GDE: loading-dependent H2O2 selectivity loss in Sn- and Sb-N-C catalysts

Abstract

Electrochemical H₂O₂ synthesis using Sn- and Sb-based single-site catalysts reveals that selectivity observed by RRDE can be lost in GDEs at higher catalyst loadings, highlighting the need for caution when translating model measurements to device-relevant conditions.
