Hydrogen storage was investigated in an activated carbon with a specific surface area of 1500 m(2)/g prepared using sucrose as carbon precursor and ammonium-form zeolite Y as template. The carbon sample exhibits a hydrogen storage capacity of 2.4 wt% at 77 K and 10 bar. The isosteric heat of adsorption was found about 8 kJ/mol at a low surface loading. CO2 adsorption isotherm at 273 K was used to characterize small micropores in the sample and was found to be more applicable than N-2 isotherm at 77 K. (C) 2008 Elsevier Inc. All rights reserved.
