In this research, a new heterogeneous molybdenum catalyst was prepared through covalent attachment of a molybdenum complex on the surface of Mo–Mt@MCM–41 material. via aminopropyl spacer and subsequent complexation with MoO(2)(acac)(2). Magnetite nanoparticles were prepared by coprecipitation of Fe (2+) and Fe (3+) salts in base condition. In the next step, the prepared magnetite nanoparticles were added to a mixture of hexadecyltrimethylammonium bromide and ammonia in water. Addition of tetraethyl orthosilicate to this mixture resulted in preparation of magnetite nanoparticles included in MCM–41 mesopores. Surface modification of the prepared material with MoO(2)(acac)(2) produced final nanomaterial, Mo–Mt@MCM–41. The prepared nanomaterial was characterized with Fourier transform infrared spectroscopy, X–ray diffraction, scanning electron microscopy.<\div>
