Microporous carbons synthesized from sucrose and melamine in the presence of molten salts present a facile strategy to design high micropore content in the carbonaceous materials. Series of nitrogen-doped samples were prepared by changing the ratio of melamine to sucrose from 0 to 2. The optimized material possesses excellent textural features, narrow micropores and high micropore volume (<0.84 nm). Furthermore, at 273 K and 1 bar, SMLK-0 uptake 197 mg/g of CO2. Present work highlights the role of micropore content in efficient adsorption. |
