Synthesis a new nanocatalyst of MoO(2)(acac)(2) supported on mesoporous MCM-41

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.
