Ultra-microporous N-doped carbon from polycondensed framework precursor for CO2 adsorption

High adsorption capacity and selectivity of microprous carbon are critical for exceptional post-combustion CO2 capture ability. Herein we report a novel strategy to prepare N-doped microprous carbon with high surface area (2363 m2 g−1 for CPTHB-7), narrow pore size distribution and high ultramicropore ratio (
