摘要
Epoxides are important chemicals and used in multiple fields.The conventional thermal-catalytic production of epoxides consumes a large amount of energy and generates abundant carbon emissions.Therefore,sustainable manufacturing technologies are highly desired.Taking advantage of renewable electricity to drive electrochemical epoxidation reactions provides a novel approach to generating value-added products in the chemicals sector.This review describes the current progress of selective electrochemical oxidation of olefins to epoxides,which is categorized according to the different reaction mechanisms.The halide-mediated method is first discussed,followed by an overview of electrochemical epoxidations with H_(2)O and O_(2)-derived H_(2)O_(2).Moreover,the existing problems in this fast-growing field and future developing directions are pointed out.This review hopes to provide inspiration for the design of electrocatalysts,electrode materials,and electrolyzers for the electrochemical production of epoxides in a sustainable manner.
