Bromide-mediated selective electrocatalytic oxidation of ethylene to ethylene glycol using non-precious metal catalyst Sn–NiSb2O6

Abstract

This study addresses fossil fuel dependency and carbon emissions in traditional ethylene glycol synthesis by developing a bromine-mediated indirect electrocatalytic oxidation strategy for ethylene using a Sn–NiSb₂O₆ catalyst. At 500 mA cm⁻², the system achieves 79% selectivity and 53% faradaic efficiency, validating the feasibility of non-noble metal catalysts for anodic selective oxidation.
