以氯化镁和氯化铝为原料,利用三嵌段共聚物F127作为络合剂,通过蒸发诱导自组装的方法合成了具有介孔结构的铝酸镁尖晶石粉体。采用XRD、TEM、氮气吸附脱附对铝酸镁样品进行了表征,表明样品为尖晶石型结构,同时700℃焙烧的铝酸镁尖晶石粉样品比表面积最大,比表面积为86.7m2.g-1。 Magnesium chloride and aluminum chloride as raw materials, the use of triblock copolymer F127 as a complexing agent, by evaporation-induced self-assembly method has been synthesized with a mesoporous magnesium aluminate spinel powder. The samples of magnesium aluminate were characterized by XRD, TEM and N2 adsorption desorption. The results showed that the sample was spinel structure, and the calcined magnesium aluminate spinel powder at 700 ℃ had the largest specific surface area and the specific surface area was 86.7m2.g. -1.
