摘要：Pure metal organic frameworks MIL-101(Cr) was directly prepared without any purification treatment using acetic acid as mineralizer. The physical structure and morphology of the material were studied by means of power X-ray diffraction(XRD), thermogravimetric(TG), scanning electron microscope(SEM) and N2 adsorption-desorption and compared with conventional MIL-101(Cr) which synthesized with hydrofluoric acid as mineralizer. The results demonstrate that the specific surface area and pore volume of the MIL-101(Cr) synthesized with acetic acid as mineralizer are superior to hydrofluoric acid as mineralizer. The MIL-101(Cr) sample synthesized with acetic acid as mineralizer is stable above 450℃, higher than the MIL-101(Cr) synthesized with hydrofluoric acid as mineralizer.
