제목 MFI-type zeolite coated ceramic tubular membrane in development of divided tubular electrochemical reactor: Efficiency analysis through  Co3+homogeneousmediatorgeneration
초록 In the present work a tubular MFI-type zeolite coated membrane (TZM) was tested in a plug flow type tubular electrochemical cell for Co2+ oxidation efficiency in high acid medium. Electrolysis of Co2+ was carried out at room temperature (20±3℃) in 4 M H2SO4 at anodic half-cell, and showed  42% Co2+ oxidation with 0.3 V higher cell voltage than the commonly used Nafion324 membrane in planar arrangement. Further, TZM membranes were robust when operated in the cell at different temperatures (10, 30 and 50℃) and current densities as no noticeable change in surface morphology was observable by SEM analysis. A long term test of the TZM at slightly elevated current density (70 mA cm2) showed increased oxidation efficiency of Co2+ to 58% compared to the traditional Nafion324 (43%).
