Covalent marriage of multi-walled carbon nanotubes (MWNTs) and β-cyclodextrin (β-CD) by silicon coupling reagents

► Amino-functional multi-walled carbon nanotubes (MWNTs) are linked up with β-cyclodextrin (β-CD) utilizing a novel grafting reagent. ► The synthesized hybrid porous materials have the unique pore and surface characteristics. ► The novel materials demonstrate the good adsorption for removing the resorcinol in water and have potentials in environmental applications.
