“…Phenolic wastewater is a common industrial wastewater that is mainly produced in industries such as coking, oil refineries, petrochemicals, etc. [ 1 , 2 ]. Due to their highly toxic and refractory properties, phenolic compounds can seriously destroy ecological systems and adversely affect human health [ 3 , 4 ].…”

In this study, the performance of a zero-gap flow-through reactor with three-dimensional (3D) porous Ti/RuO2-TiO2@Pt anodes was systematically investigated for the electrocatalytic oxidation of phenolic wastewater, considering phenol and 4-nitrophenol (4-NP) as the target pollutants. The optimum parameters for the electrochemical oxidation of phenol and 4-NP were examined. For phenol degradation, at an initial concentration of 50 mg/L, initial pH of 7, NaCl concentration of 10.0 g/L, current density of 10 mA/cm2, and retention time of 30 min, the degradation efficiency achieved was 95.05%, with an energy consumption of 15.39 kWh/kg; meanwhile, for 4-NP, the degradation efficiency was 98.42% and energy consumption was 19.21 kWh/kg (at an initial concentration of 40 mg/L, initial pH of 3, NaCl concentration of 10.0 g/L, current density of 10 mA/cm2, and retention time of 30 min). The electrocatalytic oxidation of phenol and 4-NP conformed to the pseudo-first-order kinetics model, and the k values were 0.2562 min−1 and 0.1736 min−1, respectively, which are 1.7 and 3.6-times higher than those of a conventional electrolyzer. Liquid chromatography–mass spectrometry (LC–MS) was used to verify the intermediates formed during the degradation of phenol or 4-NP and a possible degradation pathway was provided. The extremely narrow electrode distance and the flow-through configuration of the zero-gap flow-through reactor were thought to be essential for its lower energy consumption and higher mass transfer efficiency. The zero-gap flow-through reactor with a novel 3D porous Ti/RuO2-TiO2@Pt electrode is a superior alternative for the treatment of industrial wastewater.

In this study, the performance of the zero-gap flow-through reactor with 3D porous Ti/RuO2-TiO2@Pt anodes was systematically investigated for the electrocatalytic oxidation of phenolic wastewater, considering phenol and 4-nitrophenol(4-NP) as the target pollutants. The optimum parameters for the electrochemical oxidation of phenol and 4-NP were examined. For phenol degradation, at the initial concentration of 50mg·L− 1, initial pH at 7, NaCl concentration of 10.0 g·L− 1, current density of 10 mA·cm− 2 and retention time of 30 min, the degradation efficiency achieved 95.05% with energy consumption of 15.39 kWh·kg− 1, meanwhile for 4-NP, the degradation efficiency was 98.42% and the energy consumption is 19.21 kWh·kg− 1 (at the initial concentration of 40mg·L− 1, initial pH at 3, NaCl concentration of 10.0 g·L− 1, current density of 10 mA·cm− 2 and retention time of 30min). The electrocatalytic oxidation of phenol and 4-NP are conformed to the pseudo-first-order kinetics model, and the k-values were 0.2562 min − 1, 0.2075 min − 1, respectively, which were 2 or 3.6 times higher than that of conventional electrolyzer. LC-MS was used to verify the intermediates formed during the degradation of phenol or 4-NP and a possible degradation pathways was provided. The extremely narrow electrode distance and the flow-through configuration of the zero-gap flow-through reactor were thought to be essential for the lower energy consumption and higher mass transfer efficiency. The zero-gap flow-through reactor with a novel 3D porous Ti/RuO2-TiO2@Pt electrode should be a superior alternative for the treatment of industrial wastewater.
