Monolithic Porous Magnéli-phase Ti4O7 for Electro-oxidation Treatment of Industrial Wastewater

Evaluation of new ceramic electrodes based on Sb-doped SnO2 for the removal of emerging compounds present in wastewater

“…The most studied ceramic electrode is the Ebonex®, whose composition is predominantly Ti 4 O 7 (a nonstoichiometric oxide of titanium). This electrode shows good conductivity (more than graphitic carbon) and a high oxygen evolution potential [12]. Its main drawback is the change in its surface composition towards stoichiometric oxides when it is subjected to anodic polarization, which present worse properties as anode [13].…”

“…An alternative to boron-doped diamond electrodes are the ceramic electrodes. These promising electrodes present a low price, a high active area [12] due to its porosity; a high chemical stability and their manufacture is relatively easy. The most studied ceramic electrode is the Ebonex®, whose composition is predominantly Ti 4 O 7 (a nonstoichiometric oxide of titanium).…”

An electrochemical advanced oxidation process (EAOP) for the inactivation ofRhizoctonia solaniin fertigation solutions

“…Different types of electrochemical systems have been examined for microbial control, as well as for the degradation of organic pollutants (Comninellis 1994;Sirés and Brillas 2012;Chaplin 2014). Electrochemical systems used in wastewater treatment include dimensionally stable anodes (DSA) (Comninellis 1992), titanium-based (e.g., Ti 4 O 7 ) ceramics electrodes (You et al 2016), and borondoped diamond (BDD) (Comninellis 1994;Chaplin 2014;Sirés et al 2014). These technologies have been analysed as disinfection techniques for bacterial control; however, few have explored the inactivation of other biological contaminants such as fungi, which typically have higher reactive oxygenated species (ROS) demands to achieve inactivation (Ehret et al 2001;Buck et al 2003;Igura et al 2004;Cayanan et al 2009;Beeson et al 2012).…”

Anti-corrosion porous RuO2/NbC anodes for the electrochemical oxidation of phenol

“…Dense materials, such as metal electrodes, [7][8][9] metal oxide electrodes (PbO 2 , Bi 2 O 5 -PbO 5 , IrO 2 and SnO 2 ), 10,11 borondoped diamond (BDD) electrodes [12][13][14][15] and dimensionally stable anodes (DSA, i.e., Ti/IrO 2 , Ti/RuO 2 and Ti/SnO 2 ), 16 have attracted interest from many researchers because of their improved conductivity and catalytic activity. Porous electrodes, such as active carbon bres, 17 carbon nanotubes 18 and other porous materials, [19][20][21][22][23][24][25] have been proposed as a result of their high specic surface areas, electrical conductivity and chemical resistance. The porous structures of the electrode also promote the mass transport and reaction rate in a ow-through electrolytic reactor.…”
