摘 要: 以非离子表面活性剂P123为模板剂,ZrOCl2.8H2O和Ce(NO3)3.6H2O为原料,制备出高比表面的CeO2-ZrO2复合氧化物介孔材料;研究制备CeO2-ZrO2介孔材料的主要影响因素,确定最佳合成参数;分析了CeO2-ZrO2介孔材料的形成和结构。 High specific surface of CeO2-ZrOe porous material was synthesized after calcinations by the way of using block copolymers P123 as templates, zirconium chloride octahydrate (ZrOC12 -8H2 O) and cerium nitrate hexahydrate (Ce(NOa)a . 6H2 O) as raw materials. The influencing factor of CeO2-ZrO2 mesoporous structure was investigated, the optimum reaction parameters of large specific areas were determined and the mesoporous structure and morphology of CeO2 ZrO2 were examined.
