| 英文摘要 | The current study focuses on synthesis and characterization of novel functionalized anodic membranes for wastewater treatment. This membrane was prepared by first constructing a TiO2 mesoflower interlayer on a tubular porous titanium membrane and subsequently coating an antimony-doped tin oxide catalytic layer. Physical and electrochemical characterizations of the membranes were evaluated. With TiO2 mesoflower, the membrane anode obtained a higher oxygen evolution potential, 2.22 V (vs saturated calomel electrode), relative roughness factor (701.7), and electrochemical porosity (99.23%) than membrane anodes without TiO2 mesoflower. The prepared membrane anode also achieved a low charge-transfer (0.11 V) and mass-transfer resistance (0.21 V) in filtration mode. The unique features were found linked to its 3-D porous and open structure, and formation of a Ti0.2Sn0.8O2 sosoloid that had a high surface oxygen (O-ad) content. The electrocatalytic filtration performance of this membrane was also tested using methyl orange as a model organic pollutant. At a current density of 15 mA cm(-2), the membrane achieved a higher 71.0% removal of methyl orange than 58.0% for the membrane without TiO2 mesoflower. At a 58.0% removal of methyl orange, the membrane consumed a much lower energy of 0.20 kWh m(-3) than 5.88 kWh m(-3) for membrane anodes without TiO2 mesoflower. The synthesized membrane electrode filter shows promise for future applications aimed to remove organic pollutants from wastewater. (C) 2016 Elsevier Ltd. All rights reserved. |
