Design of highly efficient porous carbon foam cathode for electro-Fenton degradation of antimicrobial sulfanilamide
Abstract This work investigated, for the first time, the potential of novel biomass derived carbon foam as a suitable and efficient electrocatalytic material (as cathode) for in-situ hydrogen peroxide (H2O2) production and its applicability in electro-Fenton (EF) approach for oxidizing organic pollutants. The carbon foam cathode was prepared by polymerization and carbonization of sucrose at high temperature. The as-prepared carbon foam consists of highly porous and extremely light structure with interconnected spherical cells. It exhibited excellent electrocatalytic properties such as high conductivity, relatively high redox current and several active-sites for producing oxidizing species, …
Electro- and photo-electrooxidation of 2,4,5-trichlorophenoxiacetic acid (2,4,5-T) in aqueous media with PbO2, Sb-doped SnO2, BDD and TiO2-NTs anodes: A comparative study
Abstract In this work, the 2,4,5-T degradation in aqueous media was studied by electro- (EC) and photoelectrochemical (PEC) oxidation methods, which are two of the most important advanced oxidation processes (AOPs) for wastewater treatment. Both EC and PEC experiments were carried out in a single compartment cell under galvanostatic conditions (30 mA cm−2) at 298 K by using 0.05 M Na2SO4 + 200 ppm 2,4,5-T at pH 3 and pH 9, as model solutions. EC oxidation was performed using Sb-doped SnO2, PbO2 and boron doped diamond (BDD) as anodic materials. Besides these anodes, TiO2 in a nanotubular structure (TiO2 NTs) with or without PbO2 dispersed nanoparticles (TiO2::PbO2) were also used for PEC ox…
