Abstract

Setting the trap: A nitrogen-doped porous carbon, with a nitrogen content of up to 25.52 % and specific surface area of 948 m² g^-1 , exhibits a superior CO₂ uptake of 3.7 mmol g^-1 at 25 °C and 1 bar. Experimental and theoretical results indicate that the nitrogen-containing functional groups enhance CO₂ uptake through electrostatic, Lewis acid-base, and hydrogen-bonding interactions.
