Abstract:
By using FeSO4·7H2O as a single iron source,with the help of ammonium hydroxide as the precipitating agent,a uniform size of cubic Fe3O4 nanoparticles are prepared by the improved chemical co-precipitation method. The mesoporous Fe3O4 is prepared by a sol-gel method,which is fabricated by using CTAB as template. The Ni/mesoporous Fe3O4 catalyst is prepared by decomposing NTC on mesoporous Fe3O4. The crystalline structure,morphology and magnetic property of Ni/MFe3O4 are characterized by transmission electron microscopy(TEM),selected area electron diffraction(SAED),X-ray diffraction(XRD),X-ray Photoelectron Spectroscopy(XPS),and vibrating magnetometer(VSM). The results indicate that the Ni/MFe3O4 catalyst is highly active.The 9-phenylanthracene can be completely converted into 9-cyclohexyltetradecahydro anthracene over Ni/MFe3O4 catalyst,and the conversions of 9-phenylanthracene is up to 86.7%.
