The invention belongs to the technical field of photocatalysts, and discloses a MoS 2 @COF-Ph composite material and a preparation method and application thereof. The preparation method of the MoS 2 @COF-Ph composite material is as follows: using cyanuric chloride and p-phenylenediamine as raw materials, hydrothermally prepares COF-Ph; using thioacetamide and sodium molybdate as sulfur and molybdenum sources , mixed with COF‑Ph and then hydrothermally reacted. In the obtained composite material, a heterojunction is formed between MoS 2 and COF-Ph through a coordination bond, which provides a transfer channel for the migration of electrons and holes, reduces the recombination rate of photogenerated electron-holes, and makes the composite material with high performance. Moreover, the composite material has good stability, simple preparation process and low cost, so it has a good application prospect. |
