摘要:
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...
