In this study, tubular titanium membrane (TTM) /SnO2-Sb/SnO2-Sb-CeO2 porous anode was fabricatedand used in continuous tubular membrane reactor for electrochemical treatment of dye wastewater. Xraydiffraction (XRD), scanning electron microscopy (SEM) and high-resolution transmission electronmicroscopy (HRTEM) were used to evaluate the morphology and microstructure of the different tubulartitanium membrane. Linear sweep voltammetry (LSV) and accelerated service life test are employed toillustrate the performance of TTM/SnO2-Sb/SnO2-Sb-CeO2 porous membrane electrode. It is found thatTTM/SnO2-Sb/SnO2-Sb-CeO2 active layer on titanium membrane has compact microstructure, high over-potential for oxygen evolution (2.10 V vs saturated calomel electrode). The effects of pore diameter,applied voltage andflow rate on the electro-catalytic property of the tubular porous electrode wereinvestigated. Study shows titanium membrane reactor with an optimized pore diameter of 10 mm has thelowest energy consumption which is important for the practical application of electrochemicaltechnology. The performance of titanium tubular membrane reactor is investigated by treatingmethylene blue (MB) wastewater under the cell voltage of 3.0–4.5 V and theflow rate of 2.5–3.5 L min 1. This continuous titanium membrane electrochemical reactor using solar cell show excellent performancein treating dye wastewater and the further potential application in electrochemical synthesis.
