摘　　要：以钛酸丁酯为钛源,在碱性条件下、水/乙醇溶剂体系中通过一步水热法成功制备出了多孔分级钛酸钠纳米吸附剂材料。经过XRD、SEM和BET表征分析,表明该材料具有由纳米薄片组装而成的中空三维分级纳米微球形貌结构,其比表面积达140.60 m^2/g。经过测试,发现该材料对于亚甲基蓝具有良好的吸附性能,吸附15 min后染料的去除率可达90%以上。Porous hierarchical sodium titanate nanomaterials were successfully prepared by a one-step hydrothermal method under alkaline conditions with butyl titanate as titanium source and water/ethanol as solvent system.XRD,SEM and BET analysis showed that the material had a hollow three-dimensional hierarchical microsphere morphology consisting of Na2Ti9O19 nanoflakes,and its specific surface area was 140.60 m^2/g.The as-synthesized nanomaterials exhibited good adsorption performance for methylene blue,and the dye removal rate can reach 90%after adsorbing for 15 min.
