Heterogeneous electro-Fenton degradation of methyl orange: Multivariate optimization and voltammetric monitoring

Abstract The degradation of methyl orange (MO) was investigated using the heterogeneous electro-Fenton (het-EF) process, with synthetic goethite (S-Goe) as an iron-based catalyst in an undivided cell equipped with a Dimensionally Stable Anode (DSA) and an air-diffusion cathode. A...

Enhanced photoelectrochemical activity of detached TiO₂ nanotube films via time-controlled electrodeposition Au nanoarchitectures

Abstract TiO 2 nanotubes detached films decorated with gold nanoparticles (TiO 2 NTs-AuNPs) represent an effective strategy to enhance light harvesting in photoanodes. The films were characterized by X-ray diffraction (XRD), Raman spectroscopy, field emission gun scanning electro...
