To achieve efficient and practical scale electrosynthesis of H2O2,the designs of both catalytic material and electrochemical reactor play an equally important role.PEDOT(poly3,4-ethylene dioxythiophene),a conductive polymer,is polymerized on carbon cloth via electrodeposition method,and used in situ synthesis of hydrogen peroxide(H2O2).Scanning electron microscopy(SEM)and Fourier transform infrared spectroscopy(FT-IR)are employed to characterize the morphology and structure of the electrode.The electrode is made into a membrane electrode assembly(MEA)that is applied to the solid polymer electrolyte(SPE)electrolytic cell to explore its performance in synthesizing H2O2.The results show that PEDOT/carbon cloth has good catalytic performance for oxygen reduction to synthesize H2O2,and exhibits shorter electrode plate distances,higher H2O2 production(1,152.38 mg·L-1),and better current efficiency(89％)in SPE electrolytic cells.
