Mesoporous carbon has been studied in various fields such as catalysis, storage, and adsorption. Lignin, which is proposed as an environmentally friendly carbon precursor, is a biomass abundant in nature and has the advantage of good reactivity with benzene rings and OH groups in the structure. In this experiment, Kraft lignin was used as a sole carbon precursor, and two types of pentablock copolymer were used as templates to control the pore size of mesoporous carbon. Metal ions such as Ni2+, Zn2+, and Cu2+ were used as crosslinking agents through coordination interactions for one-pot synthesis. The samples were analyzed by TEM and BET to confirm the pore structure, size, and surface area. The presence of reduced metal particles in the structure was confirmed by XRD and EDS analysis. In addition, the CO2 uptake was analyzed by TGA. This study was supported by the Human Resource Development Programs for Green Convergence Technology funded by the Korea Ministry of Environment (MOE).
