Highly crumpled boron nitride nanosheets as adsorbents: scalable solvent-less production
journal contribution
posted on 2015-02-16, 00:00 authored by Weiwei LeiWeiwei Lei, Dan LiuDan Liu, Ying (Ian) ChenYing (Ian) ChenBoron nitride nanosheets (BNNSs), so-called “white graphene”, have recently received increasing attention, both theoretically and experimentally. Although many synthetic procedures have been proposed for the synthesis of BNNSs, finding a simple, solvent-less, catalyst-free, and large-scale production route is still a challenge. Here, a facile, solvent-less, low cost, and high yield process is developed, in which mechanical solid-state exfoliation allows scalable production of crumple BNNSs from commercial BN powders with a high surface area. Importantly, these BNNSs show unprecedentedly high adsorption of proteins described by various adsorption isotherms and kinetics models. In addition, the saturated BNNSs exhibit excellent recyclability, and maintain a high sorption capacity even after five cycles through simply regeneration process of heating in air. This easy recyclability route further demonstrates the great potential of BNNSs for water cleaning application.
