We describe a novel method for the synthesis a new magnetic bromochromate hybrid nanomaterial,Fe_3O_4@SiO_2@TEA@[CrO_3Br],as a catalyst.The physical properties,morphology and magnetic investigations of magnetic bromochromate hybrid naiiomaterials are identified by transmission electron microscopy(TEM),scanning electron microscopy(SEM) and vibrating sample magnetometer(VSM) techniques.Fourier transform infrared(FT-IR),elemental analysis,X-ray fluorescence(XRF),X-ray diffraction(XRD) were also used for structural identification.The quantity of chromium is approximately 0.38%,which confirms to the immobilization amount of[CrO_3Br]and is equal to 0.007 mol/100 g.
