| Abstract: | Oxygen vacancies enact a vital role on the visible light absorption range and electron-hole separation efficiency of the photocatalytic material.Bismuth-based glass is rich in oxygen vacancy defects.BiOCl photocatalytic material was synthesized in?situ by hydrochloric acid corrosion of bismuth-based glass,and the influence of the outer body of the glass network on the oxygen vacancy concentration was studied.X-ray diffraction(XRD),scanning electron microscope(SEM),transmission electron microscopy(TEM)and electron paramagnetic resonance(EPR)were used to characterize the structure,morphology,and oxygen vacancy concentration of the synthesized BiOCl material.The results showed that the number of oxygen vacancies of the Bi2O3-B2O3-ZnO bismuth-based glass increased with the increase of the external body composition of the network.The in?situ synthesized BiOCl will“inherit”a large number of oxygen vacancies in the glass.The degradation rate of rhodamine B was as high as 93.1%under visible light for 100 min. |
