Biomass is a consistently investigated carbon resources in carbon material fields due to their practically attractive features like eco-friendly, abundance and facile processing. To show reasonable result using biomass, we selected lignin, one of the most abundant biopolymer in the world. In this study, we targeted to surface chemistry modification; nitrogen(N) doped highly porous structure for CO2 adsorption. To make this surface reforming, nitrogen precursor was implemented on surface of lignin-derived porous carbon which was developed by pre-carbonization step including hydrothermal and chemical activation. The finally obtained material possessed ultrahigh specific surface area over 2500 m2g-1 and average pore diameter within 2 nm, with more than 1 % doping of N. By virtue of N doping and high specific surface area, the as-obtained N doped porous carbon produced excellent CO2 capture performances. |
