Preparation method of metal-organic framework material modified metal nanoparticles

The invention discloses a preparation method of metal-organic framework (MOF) material modified metal nanoparticles, used for solving the technical problem that the conventional material modificationmethod is poor in practicality. According to the technical scheme, the preparation method comprises the following steps: coating a nano aluminum powder; preparing an energetic MOF ligand, and coordinating transition metal ions; performing in-situ growth on the energetic MOF ligand; finally, washing the product with deionized water, filtering, performing freeze drying and collecting. Since the energetic MOF ligand grows on the surface of the nano aluminum powder in situ, heat release of the MOF material modified metal nanoparticles is greatly improved to 4000G g or more. The method is simple and high-efficiency, the energy performance is improved by utilizing multistage heat release capability of the system, the ignition ability and the heat release rate are regulated by selecting different energetic MOFs, and
