Preparation and application of α-FeO@MIL-101(Cr)@TiO based on metal-organic framework for photocatalytic degradation of paraquat.

In this study, a new magnetic α-FeO@MIL-101(Cr)@TiO photocatalyst was successfully synthesized. The material synthesized had been fully characterized by Fourier transform infrared spectroscopy, scanning electron microscopy, energy-dispersive X-ray spectroscopy, vibrating sample magnetometry, transmission electron microscopy, and Brunauer-Emmett-Teller isotherm methods. The X-ray diffraction analysis corroborates that nanoparticles are polycrystalline with rhombohedral and tetragonal crystal structures for FeO and TiO, respectively.
