| Abstract Scope |
Kraft softwood lignin is an abundant industrial waste product that has potential as an economic and sustainable source material for carbon capture applications. This study investigates the CO2 adsorption behavior of lignin-based carbon materials (LBCM) synthesized through three methods: pyrolysis, one-step KOH activation, and one-step NH3 gas activation. Each method produces materials with varying surface area, composition, and surface chemistry that allow us to tune the adsorption capabilities of the LBCM. We evaluate the efficacy for carbon capture of the material produced from each method through CO2 adsorption capacity and selectivity for CO2 over N2. Further, we elucidate the role of surface area and N-containing and O-containing surface functional groups on these metrics. |
