  4. Abstract:
  5. The nanocomposite of g-C 3 N 4 supported by MIL-88A has been prepared via a facile hydrothermal method. The photocatalytic performance of as-prepared composite (MIL-88A/g-C 3 N 4 ) was examined by the degradation of the Methylene Blue (MB) solution under visible light. The characterization test illustrated that the MIL-88A particles were successfully dispersed on the surface of g-C 3 N 4 structure. Photoactivity results demonstrated that the MIL-88A/g-C 3 N 4 /H 2 O 2 exhibited dramatically visible light photocatalytic performance. Hydroxyl radicals ([rad]OH) are generated by dissociation of H 2 O 2 under visible irradiation can remarkably enhance the degradation rate of MB molecules. Meanwhile, the studies of catalytic activity indicated that the conductive properties of MIL-88A/g-C 3 N 4 with the structure as well as ROS species formation simultaneously lead to the enhanced photoactivity of MIL-88A/g-C 3 N 4 composite. Furthermore, [rad]OH and [rad]O 2 – radicals species played the essential role for photodegradation MB dye. © 2019 Elsevier B.V
