membrane as shown in Fig. 12. Actually, the electrostatic attractions of the BN
surface and dye/pharmaceuticals are the reason for excellent filter performance. The
results indicated that the porous PVDF/BNNSs composite membrane has not only
great potential in effective separation of oil, pharmaceuticals, and dyes but also has
high recyclability.
4.2 Application of h-BN in Adsorption
A highly porous BNNS by a thermal treatment process without using of any catalyst
was synthesized by Lei et al. [3], which showed high surface area (1,427 m
2 .g
−1 ).
Results indicated that both porous and non-porous BNNSs have a much higher
