摘 要：Using X-ray diffraction,transmission electron microscopy,Brunauer-Emmett-Teller surface area measurement,ultraviolet-visible diffuse reflection spectra,and photoluminescence spectroscopy,the effect of mechanical milling on the photocatalytic activity of g-C3N4 photocatalyst was investigated.The rhodamine B,as a photodegrading goal,was used to evaluate the photocatalytic activity of g-C3N4.The experimental results indicate that the milling treatment is an effective method to improve the photocatalytic activity of g-C3N4.The enhanced photocatalytic activity was attributed to the improvement in catalyst’s surface area and dye adsorption on catalyst surface.Moreover,checking the luminescence properties of g-C3N4,it is found that the photocatalytic active sites on g-C3N4 are likely the same as luminescence sites.
