The invention belongs to the technical field of photocatalysis, and discloses a Z-type heterojunction photocatalytic nanomaterial with a synergistic effect of crystal planes and a preparation method and application thereof. In the material prepared by the chemical reduction method combined with the deposition method, the two-dimensional g-C 3 N 4 and the two-dimensional BiOBr nanosheets are coupled together with Ag nanoparticles as the electron transfer medium, and the surface of the catalyst is highly exposed BiOBr-{001} crystal planes, the resulting g‑C 3 N 4 @Ag@BiOBr not only follows the Z-type interfacial transfer mechanism and maintains a strong redox ability, but also the highly exposed BiOBr‑{001} crystal plane exhibits excellent crystallinity Surface synergy, with wider light absorption range, robust interfacial charge transfer, longer photogenerated electron-hole lifetime, and better degradation performance of rhodamine 6G. |
