This study successfully synthesized microporous nitrogen-doped biomass porous carbon (NPSCs) through a two-step method, utilizing cost-effective peanut shells as the source, urea nitrogen and CH3COOK activating agent. By optimizing ratio of agent carbonization temperature, pore structure surface chemical properties NPSCs were effectively tailored. Characterization results revealed that exhibited significant number micropores, attributed to critical etching effect CH3COOK. The optimal sample, NPSC-2-700, demonstrated specific area 1455.41 m2/g micropore volume 0.57 cm3/g. Notably, NPSC-2-700 achieved remarkable CO2 adsorption capacities 3.91 5.90 mmol/g at 25 0 °C, respectively, under 1 bar. Additionally, maintained exceptional performance even after ten consecutive adsorption–desorption cycles. selectivity was calculated be 43 using ideal solution theory in classic gas mixture (CO2/N2 = 15 vol %:85 %), demonstrating good dynamic capture capacity. These findings underscore promising potential materials for efficient applications.
