摘　　要：采用月桂酸为模板剂,ZrOCl_2为锆源、仲丁醇铝为铝源,利用ZrOCl_2水溶液进行水解,一步法制备了双介孔锆铝材料。采用XRD、N_2吸附-脱附和电子透射电镜(TEM)对样品进行表征。结果表明,该材料具有ZrO_2-AlO_2面心立方晶相结构和有序的双介孔孔道,较小介孔集中分布于3.5nm,较大介孔的集中分布性差,分布在12.7nm左右,其比表面积和孔容分别为379.71m^2/g和0.616cm^3/g。Bimodal mesoporous ZrO2-Al2O3waspreparedby one-step method with lauric acid as template and ZrOCl2and sec-butyl alcohol aluminum as zirconium source and aluminum source, respectively. The structure of prepared material was characterized by XRD, N2adsorption-desorption and TEM. The results indicated that the material has the ZrO2-AlO2face-centered cubic phase structure and bimodal mesoporous channels distributed at 12.7nm and 3.5nm respectively. The specific surface area and the pore volume were 379.71m^2/g and 0.616cm^3/g, respectively.
