As-resulted spherical FBNNSs/ZnO superstructures not only exhibit a high capture capacity of CO 2 around 63.4 cm 3 /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 3 /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 2 adsorption with tunable morphologies.
