The invention relates to a layered hollow ZnCdS/MoS 2 heterojunction cage, which comprises a layered polyhedron heterojunction cage composed of MoS 2 nanometer flowers and double-shell ZnCdS polyhedrons; the MoS 2 nanometer flowers are uniformly distributed on the ZnCdS polyhedron, Three-dimensional polyhedral cages of ZnCdS are used as substrates to composite MoS 2 . The preparation is as follows: using ZIF-8 as the template, the double-shell ZnCdS polyhedral cage is prepared by a two-step solvothermal method, and then the flower-like MoS 2 is uniformly grown on the double-shell ZnCdS polyhedral cage using the hydrothermal method to obtain a layered structure. The hollow ZnCdS/MoS 2 heterojunction cage can significantly enhance the absorption range and intensity of visible light; it can significantly promote the separation/migration of photogenerated carriers. Moreover, the preparation operation is simple, the cost is low, and the operation and control are easy. The layered hollow ZnCdS/MoS 2 heterojunction cage of the present invention has great potential for development and application in the fields of catalysis, energy storage, sustained drug release, wave absorption, environment and sensing. |
