Enhanced removal of organic using LaFeO-integrated modified natural zeolites via heterogeneous visible light photo-Fenton degradation.

LaFeO (LFO)-doped acid-modified natural zeolites were prepared by an impregnation-calcination method for the first time. Their effectiveness as photo-Fenton catalysts was evaluated using decolorization of Rhodamine B (RhB) as an organic model. The sample 1HNZ-30LFO was synthesized by using the support of 1HNZ, which was produced via the acid (1 N HCl) treatment of natural zeolite (NZ) at 80 °C for 3 h.
