High pressure carbon dioxide adsorption on nanoporous carbons prepared by Zeolite Y templating

Nanoporous carbons were synthesized by chemical vapor deposition using furfuryl alcohol/butylene as a carbon source and zeolite Y as a hard template (ZYC). The ZYC were characterized by PXRD, N(2) sorption, and SEM. The carbon materials exhibited predominant microporosity, and the specific surface area increased from 2563 to 3010 m(2) g(-1) as the pyrolysis temperature was raised from 800 to 1000 degrees C. ZYC prepared at 1000 degrees C showed a CO(2) adsorption capacity of 986 mg g(-1) (adsorbent) at 40 bar 298 K, which surpasses the capacities of commercial carbons and mesoporous carbon CMK-3, and closely approaches the best performance of the metal organic framework MOF-177. The CO(2) adsorption capacities of the adsorbents were found to be closely correlated with the BET surface areas of the materials tested. (C) 2011 Elsevier B.V. All rights reserved.
