Highly Nitrogen-Doped Porous Carbon Derived from Zeolitic Imidazolate Framework-8 for CO2 Capture.

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.
