Abstract

Porous carbon material adsorbents are one of the effective methods for carbon dioxide (CO2) capture and storage (CCS). In order to realize its application, it is urgent to find economical and efficient raw materials for preparing porous carbon materials. In this study, porous carbon materials were successfully prepared using lignocellulosic components as a carbon source and a mild Kac adsorbent. The CO2 adsorption performance of these materials was then tested. LCH-1 exhibited excellent CO2 adsorption performance and stability in all samples. The microporosity of LCH-1 is as high as 84.48%, and its CO2 adsorption capacity under 1 bar at 273K and 298K is 4.94 mmol/g and 3.31 mmol/g, respectively.
