Abstract Because the g-C3N4 have sufficient raw materials, high photocatalytic activity, low stability and price benefits, so the class of semiconductor materials it has sparked great interest to study。 This paper studies prepared by hydrothermal method g-C3N4/Ag3PO4, and to study its visible light photocatalytic properties。 By X-ray diffraction (XRD) crystal structure of the test sample, you can use a scanning electron microscope (SEM) to observe its shape, but also by UV spectrophotometer for measuring a variety of products for optical characteristics。 Photocatalytic prepared to take advantage of rhodamine B and methylene blue (MB) and methyl orange (MO) light degradation。 Compared to the pure photocatalyst g-C3N4, results showed that g-C3N4/Ag3PO4 composite photocatalyst exhibit enhanced photocatalytic activity。 This should be attributed to enhanced composite photocatalyst can promote good photo-generated electron separation。 Significance of this paper is that through the g-C3N4/Ag3PO4 composite photocatalyst catalytic degradation of the samples to prove that the synthesized composite photocatalyst has a significant role in dealing with environmental pollution。
Keywords: g-C3N4 Ag3PO4 photocatalytic degradation of dye
