Abstract

Designing highly efficient photocatalysts is significantly important to degrade the harmful pollutions in water. In this study, photocatalyst of Fe3O4-ED-rGO with dissolved HPV was successfully prepared and electron microscopy characterization revealed that large number of single tungsten/vanadium atom oxide (ST/VAO) was homogeneously deposited on Fe3O4 nanoparticles in SMAO-MrGO-ED sample and occupied the bivalent Fe2+ sites. Meanwhile, phase analysis confirmed that the Fe3O4 nanocomposites were mostly conversed from the reducted Fe2O3 by the hydrolysis of rGO-ED-HPV. Such a highly dispersed monatomic adsorption on the bivalent Fe2+ of polycrystalline SMAO-MrGO-ED nanocomposite not only benefits for the visible light absorption from 2.7 eV to 2.10 eV, but also offers abundantly active sites to get the highest activity of 98.43% and 98.12% for ciprofloxacin (CF) and ibuprofen (IBF) photodegradation, respectively. All these discoveries give us a new insight to design the photocatalysts with high photodegradation efficiency, low cost, short reaction time and good reusability.
