Abstract

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