Treated by metal oxides, amine salts, etc. to achieve functionalization. Although the substrate includes carbon nanotubes and molecular sieves, the amount of carbon dioxide adsorbed in this method is relatively low, and the maximum is only 0.17 mmole/g (7.48). Mg/g), and this patent only discloses that the adsorbent itself' is not further combined with the device. Furthermore, ''Carbon dioxide capture process with regenerable sobents (Pat. #: US 6,387,337 Bl)'' in Pennline and Haffman (2002) is made using alkali metals or alkaline earth metals.
