Abstract

3D functionalized flower-like boron nitride nanosheets (FBNNSs) were synthesized by a novel template-free method involving “cylinder compressing”. Due to the high surface area (1114 m2 g−1), pore volume (0.7 cm3 g−1), hierarchical pore distributions, and abundant edge groups (–OH and –NH2), the 3D functionalized FBNNSs displayed excellent NH3 and CO2 adsorption up to 91 mg g−1 and 37.9 cc g−1 (74.4 mg g−1) at 1 bar, respectively. Moreover, the reusable performance of the material for gas adsorption was maintained for 10 cycles, indicating the stable structure of the FBNNSs. In addition, the adsorption mechanism was mainly explained by Lewis acid/base interactions, weak van der Waals interactions, and H-bonds. The combination of the enhanced adsorption capacity, excellent regenerability, and extraordinary chemical and thermal stability means that 3D FBNNSs possess huge potential for implementation in practical NH3 and CO2 capture.
