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

Abstract

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, N2 sorption, and SEM. The carbon materials exhibited predominant microporosity, and the specific surface area increased from 2563 to 3010m2g−1 as the pyrolysis temperature was raised from 800 to 1000°C. ZYC prepared at 1000°C showed a CO2 adsorption capacity of 986mgg−1adsorbent at 40bar 298K, 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 CO2 adsorption capacities of the adsorbents were found to be closely correlated with the BET surface areas of the materials tested.
