Abstract: A series of porous carbon materials was synthesized via high temperature pyrolysis from well-defined and thermally stable precursors, namely porous organic frameworks(POFs), in inert atmosphere. The porous carbon materials showed enhanced gas adsorption capacities together with increased heat of adsorption and stronger affinity between the frameworks and the gases as compared to the precursor materials. To exemplify, sample C-POF-TBBP-1000 with a high BET surface area of 1290 m2/g can adsorb 2.8 mmol/g CH4(273 K, 101.325 kPa), 5.4 mmol/g CO2(273 K, 101.325 kPa) and 2.2% H2(mass fraction, 77 K, 101.325 kPa), thereby surpassing most other porous adsorbent materials reported till date. The study highlights the potential of porous carbons derived from novel porous organic framework structures for gas adsorption applications.
