Enhancement of the heterogeneous photo-Fenton performance of GO/MIL-100(Fe)@Fe₃O₄ heterostructures for erythromycin degradation through accelerating Fe(ii) generation.

ABSTRACT: The slow rate of the Fe³⁺/Fe²⁺ cycle has decreased the efficiency of photo-Fenton technology for wastewater treatment. Here, a novel GO/MIL-100(Fe)@Fe₃O₄ heterostructure was constructed by growing Fe₃O₄ nanoparticles and MIL-100(Fe) onto GO, thus accelerating the Fe³⁺/Fe²⁺ cycle and improving catalytic activity, and it was used as a heterogeneous photo-Fenton catalyst for ERY degradation. The catalyst was fully characterized by TEM, XRD, Raman spectroscopy, XPS, N₂ adsorption-desorption and UV-vis DRS. The influences of initial solution pH, H₂O₂ concentration and catalyst dosage on ERY degradation were investigated. Under optimal conditions (initial pH of 4.03, 10.0 mM H
