Nature Catalysis, Published online: 12 May 2026; doi:10.1038/s41929-026-01535-6 Direct electrocatalytic oxidation of propylene in aqueous solution has been limited to precious-metal catalysts in halogenated electrolytes. Now, a perovskite oxide has achieved 40% Faradaic efficiency towards propylene oxide and glycol using water as the oxygen source in a phosphate/polyphosphate electrolyte.
