Homogeneous silver catalyst for propylene electrooxidation to propylene glycol.

ABSTRACT: Electrically-powered synthesis provides a sustainable approach for propylene oxidation to propylene oxide and propylene glycol in aqueous medium using water as the oxygen source, which can substitute conventional energy-intensive process that relies on hazardous oxidants. However, current electrosynthesis is suffering from expensive catalysts, low current density and Faradaic efficiency. Herein, guided by accidental finding of Ag⁺ showing activity for propylene electrooxidation to propylene glycol and following mechanistic understanding, we report 1,2,3-triazole-chelated Ag catalyst with improved current density (15.8 mA/cm²) and Faradaic efficiency (62.5%), comparable with heterogeneous Pt and Pd catalysts using 30-fold less expensive metal. We experimentally and the
