摘要
为了实现高效、实际规模的H2O2 电合成,催化材料和电化学反应器设计发挥着同样重要的作用.通过电沉积方式在碳布(Carbon Cloth,CC)上聚合导电聚合物聚 3,4-乙烯二氧噻吩(PEDOT)用于原位合成过氧化氢(H2O2),利用扫描电子显微镜(SEM)、傅里叶变换红外光谱(FT-IR)对电极形貌结构进行表征.将电极制作为膜电极组件(MEA)并应用于固体聚合物电解质(SPE)电解池,探究其合成H2O2 的性能.结果表明,PEDOT/CC具有良好的催化氧还原合成H2O2 的性能,并且在SPE电解池中表现出更短的极板距离、更高的H2O2 产量(1152.38 mg/L)以及更优的电流效率(89％).
Abstract
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.
