چکیده انگلیسی

We describe a novel method for the synthesis a new magnetic bromochromate hybrid nanomaterial, Fe3O4@SiO2@TEA@[CrO3Br], as a catalyst. The physical properties, morphology and magnetic investigations of magnetic bromochromate hybrid nanomaterials 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 [CrO3Br]− and is equal to 0.007 mol/100 g.

A new magnetic bromochromate hybrid nanomaterial with triethylamine surface modified Fe3O4 nanoparticles is prepared and fully characterized by XRF, XRD, FT-IR, UV/vis, SEM, TEM and VSM.Figure optionsDownload as PowerPoint slide
