CO2 capture and gas separation on boron carbon nanotubes

- CO2 molecules form relative strong interactions with these B2CNT.
- CH4, N2 and H2 molecules can only form weak interactions with B2CNTs.
- The B2CNT can be used as a promising material for CO2 capture.
- The B2CNT adsorbent has very high selectiveness for gas separation.
- Negative charges can enhance the B2CNT's ability of CO2 capture and selectiveness for gas separation.
