Abstract Fenton processes allow to degrade and mineralize toxic organic contaminants, yet classical require continuously adding hydrogen peroxide ferrous ions, costly solution pH adjustment, treatment of secondary iron sludge pollution. Heterogeneous electro-Fenton deliver oxidizing radicals with only oxygen electricity consumed. Bifunctional catalysts the synthesis activation simultaneously, e...

Abstract In this study, the Fenton/adsorption of dye effluent containing Levafix blue has been carried out via a cost-efficient and eco-friendly heterogeneous Fenton solar-Fenton methods. Alum sludge, water treatment by-product were successfully collected calcined to 400 °C (AS400) tested for use as catalyst in process. X-ray diffraction, Scanned electron microscopy techniques applied investiga...

Copper nanoparticles (Cu NPs) supported on diamond nanoparticles (D NPs) previously purified by Fenton treatment (Cu/D) followed by annealing with hydrogen (Cu/DH) are highly efficient and reusable heterogeneous catalysts for hydrogenation of styrene to ethylbenzene with the minimum productivity value of 30,617 cycles.

We investigated the performance of a heterogeneous Fenton-like reaction (ZVI-Fenton, i.e. , ZVI + H 2 O where = zero-valent iron) towards removal potentially pathogenic bacteria in wastewater (WW). The effectiveness process was live (measured by flow cytometry) as well (identified 16S rRNA amplicon sequencing), antibiotic resistance genes and class 1 integrons (assessed qPCR). ZVI-Fenton result...
