Enhanced adsorption of aromatic chemicals on boron and nitrogen co-doped single-walled carbon nanotubes†
Abstract
By altering surface electron distribution of carbon nanotubes and creating structural defects, co-doping with B and N promotes polarization of π electrons on carbon nanotube surfaces and thus, generates more abundant π-electron-rich and π-electron-deficit sites that are beneficial for the adsorption of both π-acceptor and π-donor aromatic compounds.
