Preparation and Photocatalytic Property of SO42-/TiO2, SO42-/Fe2O3 Nano-Particles

SO42-/TiO2, SO42-/Fe2O3 nanoparticles were prepared by the impregnation precipitation method. The X-ray diffraction (XRD), scanning electron microscopy (SEM), and energy disperse spectroscopy (EDS) results showed that the uniform size of SO42-/TiO2, SO42-/Fe2O3 nanoparticles with high purity, good dispersivity and particle size range from 50nm to 200nm. A comparative study between SO42-/TiO2 and SO42-/Fe2O3 nanoparticles applied in the photocatalytic experiment on unsymmetrical dimethylhydrazine (UDMH) wastewater was carried out.
