The present invention provides an In—NH 2 /g-C 3 N 4 nanocomposites with visible-light photocatalytic activity and application thereof, which can effectively remove organic pollutants (such as tetracycline) in water. First, the graphite phase carbonitride carbon (g-C 3 N 4 ) was obtained by thermal condensation, and g-C 3 N 4 nanosheet was prepared by thermal oxidative etching. Then, acicular MIL-68(In)—NH 2 (In—NH 2 ) was grown in situ on the surface of g-C 3 N 4 nanosheet by solvothermal method. The In—NH 2 /g-C 3 N 4 nanocomposites with high visible-light photocatalytic activity were obtained. The CNNS firstly was prepared in the present invention, which is beneficial to the needle-like In—NH 2 growing on the surface of CNNS and having close interfacial contact with each other, forming a heterojunction, promoting the separation of photogenerated electrons and holes pairs, and enhancing visible-light photocatalytic degradation of organic pollutants. The nanocomposites show high structural stability and reusability, which has great potential in the field of water remediation. |
