Original Abstract Submitted
Methods and systems for the electrochemical epoxidation of alkenes to generate an epoxide are described herein. Said methods and systems comprise: contacting an anode comprising an oxygen atom transfer electrocatalyst with an alkene in the presence of an electrolyte comprising water; applying a voltage to the anode and a cathode to generate the epoxide; wherein the oxygen atom transfer electrocatalyst comprises an at least partially oxidized palladium-platinum alloy characterized by the formula FX1: PdPtO; wherein y is greater than 0 and less than 1; z is greater than 0 and less than 1; wherein the sum of y and z is equal to 1; and x is selected from the range of 0 to 2. The methods and systems disclosed herein comprise a significant advancement in the electrocatalytic epoxidation of alkenes in aqueous and mixed electrolytes using water as the oxygen atom transfer source.
