摘　　要：以阳极氧化铝模板(AAO)为硬模板,嵌段聚合物P123为软模板制备一维稀土介孔纳米材料。用硝酸镨、P123、乙醇和水的混合溶液作为前驱体,与AAO模板组装,经高温煅烧后,在AAO模板的孔洞中生成一维Pr6O11介孔纳米材料。采用TEM、XRD、XPS等分析测试手段对合成产物进行了表征。结果表明:制备的一维Pr6O11纳米材料表面有分布均匀的介孔,有较大的比表面积并且对刚果红水溶液的吸附作用非常明显,对刚果红的吸附,去除率最高可达97.24%。Anodic aluminum oxide （AAO） as hard template and block polymers P123 acted as soft template, the one-dimensional rare earth mesoporous nanomaterials were synthesized. The mixture of praseodymium nitrate, P123, ethanol and water used as precursors, the nano channel of AAO template were filled with precursors and annealed, one dimensional Pr6O11 mesoporous nanomaterials were obtained in the hole of the AAO template. The synthesized products were characterized by TEM, XRD, XPS, and other analytical testing methods. The one-dimensional Pr6O11 have mesoporous strcture, uniformly distributed and larger surface area. The one-dimensional Pr6O11 have a good adsorption capacity for Congo Red solution, and the maximum adsorbent rate can reach 97.24%.
