Abstract
We report a versatile fabrication method, detailed material characterization, pore architecture formation patterns, and surface functionality of MIL-100Al-derived porous carbons. Oxygen-doped porous carbons were prepared via carbonization of MIL-100Al, MIL-100Al/F127 composite, and MIL-100Al/KOH mixture. Microscopy tools showed different Al2O3 composite patterns and morphologies in the carbon particles, and a coherent discussion of versatile fabrication methods on carbon textural properties is demonstrated. The obtained porous carbons have a large specific surface area (up to 1097 m2 g−1), well-developed narrow microporosity (up to 92% of the pore volume arises from micropores), and excellent CO2 adsorption capacities of 6.5 mmol g−1 at 273 K and 4.8 mmol g−1 at 298 K at an ambient pressure, which is among the highest reported so far for the MOF-derived carbons. Furthermore, excellent CO2/N2 selectivity of 45, CO2/CH4 selectivity of 14.5, and CH4/N2 selectivity of 5.1 were achieved at 298 K and 1 bar. Kinetic selectivity was also calculated, in which high CH4/N2 selectivity (up to 11) was reached at 273 K and 1 bar. Potent gas separation performance and outstanding regenerability, demonstrated by breakthrough simulation and adsorption–desorption cycling tests, enable these MOF derived porous carbons to function as suitable solid adsorbents for CO2 capture from flue gas and bio-gas upgradation.
