Enhancing catalyst stability: Immobilization of Cu-Fe catalyst in sodium alginate matrix for methyl orange removal via Fenton-like reaction.

This study aims to enhance the stability and effectiveness of heterogeneous catalysts in Fenton-like reactions, explicitly addressing the acidity limitations inherent in traditional Fenton processes. Copper-iron was synthesized through co-precipitation, and a catalyst bead was produced from hydrogel formation. X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS) confirm phases in the bimetallic Copper-iron, aligning with the intended composition.

Degradation of formaldehyde by photo-Fenton process over n-ZVI/TiO catalyst.

The degradation of formaldehyde in a photo-Fenton reaction was studied using n-ZVI/TiO as the catalyst. The effects of %n-ZVI loading, catalyst dosage, HO, and pH on formaldehyde degradation were studied. The n-ZVI/TiO catalysts were prepared by impregnation with chemical reduction, and their catalytic activity was evaluated in a batch reactor under UVC light.
