The invention belongs to the field of preparation technology of nano-porous materials, and relates to a preparation method of a spinel-type magnetic aerogel material. By mixing ferric salt and divalent metal salt, after hydrolysis reaction, coagulant epoxide is introduced, and spinel-type magnetic aerogel precursor is obtained by sol-gel and supercritical drying, and then in Air heat treatment is performed in a muffle furnace, thereby finally preparing a spinel-type magnetic aerogel material. The invention has the advantages of low cost of materials and convenient process, low energy consumption, simple process, and easy realization of large-scale production. |
