Without any extra directing agents or surfactants, three-dimensional (3D) hierarchically cubic and spherical morphologies of functionalized boron nitride nanosheets (FBNNSs)/ZnO superstructures have been controlled successfully via the evaporation-induced solvothermal synthesis. As-resulted spherical FBNNSs/ZnO superstructures not only exhibit a high capture capacity of CO around 63.4 cm/g (124.5 mg/g) from 0 to 1 bar at 273 K but also show a good reusability of 10 cycles with an average removal ability up to 58.9 cm/g (115.7 mg/g). The excellent adsorption property can be further explained by the chemisorption, van der Waals interaction, and H bonds from the surface of ZnO and the in-plane and edged amino groups of FBNNS. Therefore, the preparation of 3D FBNNSs/ZnO superstructures provides a new and promising material for CO adsorption with tunable morphologies.
在没有任何额外导向剂或表面活性剂的情况下，通过蒸发诱导溶剂热合成，成功地控制了功能化氮化硼纳米片（FBNNS）/ZnO 超结构的三维（3D）分级立方和球形形态。所得的球形 FBNNS/ZnO 超结构不仅在 273 K 时从 0 到 1 巴下表现出高的 CO 捕获能力，约为 63.4 cm/g（124.5 mg/g），而且还具有良好的 10 次循环可重复使用性，平均去除能力高达 58.9 cm/g（115.7 mg/g）。这种优异的吸附性能可以进一步通过 ZnO 表面的化学吸附、范德华相互作用和氢键以及 FBNNS 的平面和边缘氨基基团来解释。因此，3D FBNNS/ZnO 超结构的制备为具有可调形态的 CO 吸附提供了一种新的、有前途的材料。
