In this study, lignin byproducts are converted into high-performance porous carbon materials for various applications, including CO2 adsorption. The main focus of the research was to explore optimal thermal treatment processes using activating agents such as hydroxides (NaOH, KOH) and carbonates (Na2CO3, K2CO3). The resulting carbonized lignin exhibited different pore structures and specific surface areas depending on the activating agents and temperature used. In particular, when hydroxides were applied, the highest surface area achieved was 2,700 m2/g, about 150 times higher than that of kraft lignin. In addition, the optimized carbonized lignin also significantly increased its CO2 adsorption capacity, reaching 3.6 mmol/g, which is 21 times higher than that of kraft lignin. It also exhibited excellent performances in removing dyes and chromium. Therefore, these findings suggest that lignin-derived carbon materials have great potential as efficient dyes, metal ions, and CO2 adsorbents.
