Novel photocatalysts of fly ash cenospheres supported BiOBr hierarchical microspheres with high photocatalytic performance

A novel fly-ash cenospheres (FACs) supported BiOBr hierarchical microspheres were successfully prepared via a facile one-pot solvothermal method. The as-prepared samples were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive spectrometry (EDS), UV–visibl...

Description
Summary:A novel fly-ash cenospheres (FACs) supported BiOBr hierarchical microspheres were successfully prepared via a facile one-pot solvothermal method. The as-prepared samples were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive spectrometry (EDS), UV–visible diffuse reflectance spectroscopy (DRS) and N2 adsorption–desorption isotherms. The results indicated that polyvinylpyrrolidone (PVP) facilitated the loading of BiOBr hierarchical microspheres. Based on the photodegradation tests under visible light irradiation (λ>420nm), the photocatalytic property of PVP/BiOBr/FACs photocatalysts was superior to that of BiOBr/FACs.
