• Carbon nanotubes
• Capillary condensation
• Nitrobenzene
• Adsorption

The microstructure changes of carbon nanotubes modified by mechanical ball milling and the effect on the adsorption of nitrobenzene were studied. The experimental results demonstrated different lengths of short open-ended carbon nanotubes could be prepared by mechanical ball milling. The extent of shortening and opening of carbon nanotubes increased with the milling time. The aggregated pores size of carbon nanotubes sharply decreased after milling, while the size of inner cavity enlarged slightly. The saturated adsorptive amount of carbon nanotubes after milling 30 h for nitrobenzene improved obviously from 19.8 to 41.5 mg g(-1) compared to unmilled sample. The capillary condensation on both inner cavity and compressed aggregated pores played an important role in liquid phase adsorption.
