以SBA-15为硬模板合成球形介孔氧化锆及其结构表征
首发时间:2016-01-07
摘要:以SBA-15为硬模板,成功制备了含硅的球形介孔氧化锆材料,并通过XRD、N2吸附-脱附、IR和SEM等多种表征手段对合成样品的物化性能和结构进行了表征。研究结果表明, 合成的含硅介孔氧化锆材料为大小不一的球形,该材料具有较高的热稳定性和大的比表面积,经过700℃焙烧后,其比表面积仍可达342m2/g,高的比表面积主要归结于碳物种和硅物种的存在,这种球形的介孔氧化锆经硫化后可在精细化工、药物合成等领域具有潜在的应用前景。

Synthesis and Characterization of spherical mesoporous zirconia using SBA-15 as hard template
Abstract:A spherical meso-structured zirconia material was prepared by using SBA-15 containing carbonized surfactant P123 in the mesopores as assisted template. The resultant ZrO2 material was characterized by XRD, N2 adsorption-desorption, IR,SEM, EDX. The mesoporous zirconia has high thermal stability and larger surface area of 342m2/g after the calcined temperature of 700℃, due to the exsitence of carbon and silicon. This new spheric mesoporous zirconia material may have a more extensive application in fine chemical, pharmaceutical industries processes after sulfated.
