摘 要：Zn（Ⅱ）-doped graphitic carbon nitride（g-C3 N4）with high photodegradation activity was prepared by one facile step. The morphology and structure of the prepared Zn（Ⅱ）-doped g-C3 N4 were investigated, and the results showed that Zn（Ⅱ） could self-disperse during the pyrolysis process and Zn–N bond was formed between g-C3 N4 and Zn. The dope of Zn（Ⅱ） influenced the structure of g-C3 N4.The performance of photocatalytic activity of Zn（Ⅱ）-doped g-C3 N4 series indicated that the doped g-C3 N4 with a small quantity of Zn（0.10 wt%） exhibits the best photocatalytic performance. The photodegradation activity for methyl orange was 2 times higher than that of pure g-C3 N4.However, the photocatalytic activity decreased with the further increased content of Zn, which may be attributed to the structure change of g-C3 N4 and the interaction of Zn–N bond between Zn and g-C3 N4. Moreover, Zn（Ⅱ）-doped g-C3 N4 showed good recycling photocatalytic stability.
