“…Moreover, the total mineralization to CO 2 and H 2 O as well as the optimal faradic efficiency was strictly obtained by using high oxygen over-potential anodes, such as Tin dioxide SnO 2 (Ramalho et al, 2010), lead dioxide PbO 2 (Belhadj-Tahar and Savall, 1998;Weiss et al, 2008) and boron-doped diamond BDD, which brought about different removal organic matter efficiencies (Michaud et al, 2003;Zhao et al, 2010;Da Silva et al, 2013). Non-active anodes, as BDD, is a new anode material and possesses technologically important characteristics such as an inert surface with low adsorption properties, remarkable corrosion stability and an extremely wide potential window in aqueous medium (Panizza and Cerisola, 2009;Da Silva et al, 2013;Dos Santos et al, 2014).…”

“…So, there is an urgent need to develop efficient and economical methods to simultaneously remove organic and inorganic pollutants from such effluents. Due to their toxicity and potential carcinogenic effect, they may cause irreparable damage not only to human health but also to the environment (Diya'uddeen et al, 2011;Rocha et al, 2012;Da Silva et al, 2013).…”

“…In the existing literature it has been stated that the optimal performance of MFCs is obtained when the pH is within the range of 6.5-8.5, because this range stimulates the growth of electrogenic microorganisms [8]. MFC operation is also strongly affected by temperature, either due to kinetics and mass transfer (activation energy and mass transfer coefficient) [9], thermodynamics (free energy and electrodes potential), the external resistance [10], the feed rate [11,12] hydrodynamics [13], anode geometry [14] or the nature and the distribution of microbial communities [15,16].…”

In this work, the start-ups of air-cathode microbial fuel cells (MFCs) seeds with conventional activated sludge cultivated at different solid retention times (SRTs) are compared. A clear influence of the SRT of the inoculum was observed, corresponding to an SRT of 10 days to the higher current density exerted, about 0.2 A m -2 . This observation points out that, in this type of electrochemical device, it is recommended to use high SRT seeds. The work also points out that in order to promote an efficient start-up, it is not only necessary to use high SRT seeds, but also to feed a high COD concentration. When feeding 10000 ppm COD and keeping SRT of 10 d differences of current densities up to 0.1 A m -2were observed within a cycle. Additionally it was observed that SRT influences direct and indirect electron transfer mechanisms, being the direct mechanisms the most relevant ones, accounting for more than 95% of the total electricity production.

“…Among the popular electrochemical catalysts (e.g. boron-doped diamond (BDD) [13], RuO 2 [14], Ti 4 O 7 [3,15], IrO 2 [16], PbO 2 [17], and Sbdoped SnO 2 (ATO) [18]), ATO is considered an excellent candidate owing to its high oxygen evolution potential (OEP), 1.8 V (vs saturated calomel electrode, SCE) [18], easy in preparation and cost efficiency. Electrocatalytic properties (e.g.…”

Keywords:functionalized tubular porous titanium membrane TiO 2 mesoflower interlayer electrocatalytic filtration anodic catalytic oxidation A B S T R A C T The current study focuses on synthesis and characterization of novel functionalized anodic membranes for wastewater treatment. This membrane was prepared by first constructing a TiO 2 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 TiO 2 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 TiO 2 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 Ti 0.2 Sn 0.8 O 2 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 À2 , the membrane achieved a higher 71.0% removal of methyl orange than 58.0% for the membrane without TiO 2 mesoflower. At a 58.0% removal of methyl orange, the membrane consumed a much lower energy of 0.20 kWh m À3 than 5.88 kWh m À3 for membrane anodes without TiO 2 mesoflower. The synthesized membrane electrode filter shows promise for future applications aimed to remove organic pollutants from wastewater.
