Efficient photo-assisted Fenton catalysis mediated by Fe ions on Nafion membranes active in the abatement of non-biodegradable azo-dye

Abstract

Highly dispersed Fe ions on Nafion membranes are shown to decompose H₂O₂ with similar kinetics as found for homogeneous solutions containing Fe³⁺ ions during the photo-assisted Fenton degradation of Orange II, avoiding the drawbacks of the homogeneous treatment.
