【摘要】 本文中以Ti（SO₄）₂·6H₂O为钛源合成了具有较大孔径的氧化钛层柱磷酸锆和氧化钛层柱磷酸-苯瞵酸锆。用XRD,IR,TG-DTG,³¹P MAS NMR和N₂吸附脱附对样品进行了表征,结果表明层板中引入苯环减弱了氧化钛柱与磷酸锆层板之间的相互作用,使氧化钛层柱磷酸锆的热稳定性达到了450℃。在烃类的催化氧化反应中,氧化钛层柱磷酸锆具有优于TiO₂的选择氧化性能,并在反应中表现出较好的稳定性。更多还原

【Abstract】 In this paper, titania-pillared zirconium phosphonate and titania-pillared zirconium phosphonate andphenylphosphonate were synthesized using Ti（SO₄）₂·6H₂O as Ti source. XRD, IR, TG-DTG, ³¹P MAS NMR and N₂adsorption/desorption were used to characterize the samples. The results indicated that the phenyl group introduced tothe sheets of zirconium phosphate decreased the interaction between the sheets and titania pillars, enhanced the thermalstability of titania pillared zirconium phosphate up to 450℃. In the catalytic oxidation of hydrocarbons, titania-pillaredzirconium phosphonate and phenylphosphonate had a catalytic activity higher than TiO₂, they also showed a goodstability during the reaction.更多还原
