摘要
三维(3D)多级结构纳米材料因其性能优异而备受人们关注,已经在储能、催化、水处理等领域得到广泛应用。本文利用表面活性剂(EDTA-2Na)辅助水热方法成功制备出了由纳米棒组装而成的多级γ-Ba B_2O_4中空微球,产品粒径分布均匀(Fig.1(a))。多级γ-BaB_2O_4中空微球具有较大比表面积46.25 m~2 g~-1(Fig.1(b))。利用多级γ-BaB_2O_4中空微球为吸附质,吸附含有Pb~(2+)离子的模拟废水溶液(50 mg L~(-1)),Pb~(2+)离子去除率可达80%,最大吸附量qm达到101 mg g~(-1),显示出较好的吸附效果(Fig.1(c))。
Hierarchical three-dimensional(3D) nanoarchitectures have attracted much concern for their wide applications in energy storage, catalysis, water treatment, etc., owing to their outstanding properties. Uniform hierarchical γ-Ba B_2O_4 hollow microspheres self-assembled by one-dimensional(1D) nanorods were successfully synthesized by a facile surfactant-assisted(EDTA-2Na) hydrothermal method(Fig. 1(a)). The hierarchical γ-Ba B_2O_4 hollow microspheres exhibited a large specific surface area as 46.25 m~2 g~(-1)(Fig. 1(b)), which demonstrated good adsorption performance when employed as the adsorbents for the removal of Pb~(2+) from the simulated waste water(50 mg L~(-1)), with the removal efficiency up to 80% and the maximum adsorption capacities(qm) of ca. 101 mg g~(-1)(Fig. 1(c)).
