Cobalt-containing nanocomposites based on zeolites of MFI framework type

Here we report the synthesis of cobalt-containing magnetic nanocomposites based on ZSM-5 zeolite and investigation of their magnetic properties. Preparation of the samples was carried out by thermal decomposition of cobalt carbonyl inside zeolite channels. It was shown that Co@ZSM-5 samples possess ferromagnetic behavior at room temperature owing to formation of anisotropic nanostructures in pores of the matrix.
