Abstract

A cathodic indirect electro_oxidation system was established for indirect electro_oxidize dimethyl sulfoxide to dimethyl sulfone with electro_reduction generated H 2O 2 catalyzed by the pertungstate/tungstate(WO 5 2- /WO 4 2- )redox mediator. Influences of current density,pH,temperature,and the current efficiencies etc. on the cathodic indirect electro_oxidation of dimethyl sulfone were investigated for determining optimum reaction conditions.The current efficiency reached more than 70%.Mother_liquid could be recycled to use without pollution.
