采用聚氧乙烯型非离子表面活性剂 ( PEO)为模板剂 ,超临界乙醇为介质 ,在不同条件下 (各种 PEO,不同 p H值和络合剂 )合成了类似于 MSU的介孔氧化锆 .XRD,N2 物理脱吸附曲线 ,TEM及选区电子衍射证明该介孔氧化锆骨架为四方晶型 ;改变表面活性剂类型、络合剂及 p H可调变介孔氧化锆的 BET表面积与孔分布
Using polyoxyethylene nonionic surfactant (PEO) as template and supercritical ethanol as medium, mesoporous oxidation similar to MSU was synthesized under different conditions (various PEO, different p H value and complexing agent) Zirconium. XRD, N2 physical desorption curve, TEM and selected area electron diffraction prove that the mesoporous zirconia framework is tetragonal. Changing the BET surface area of surfactant type, complexing agent and p H adjustable mesoporous zirconia with Hole distribution
