The photocatalytic composite of g-C3N4/ZnO with different g-C3N4 content have been prepared by thermopolymerization method. The catalysts are characterized and analyzed by SEM, XRD, UV-Vis, BET and other analytical methods. The results show that g-C3N4/ZnO composites caused the red shift of the absorption band edge of ZnO, which increased the absorption of visible light and the separation rate of photogenerated electron-hole pairs. It is found that the H2 production rate of 25% g-C3N4/ZnO sample is best with 306.25 μmol∙h-1∙g-1, which is 4.6 times higher than of g-C3N4. |
