| heal.abstract | Novel Periodic Nanoporous Organosilicas (PNOs) synthesized by direct co-condensation of tetraethylorthosilicate and triethoxy(naphthalen-1-yl)silane (as described in detail in part I) were evaluated for their hydrogen and methane storage ability. The naphthalene-based PNO materials exhibit regular hexagonal arrangement of uniform pores, high naphthalene content up to 17 wt.%, specific surface areas above 1000 m(2)/g and pore size distributions in the microporous/mesoporous boundary. Methane and hydrogen storage properties, at different temperatures, have been investigated for these samples by Sievert-type apparatus. The samples exhibit a reversible methane/hydrogen surface excess adsorption capacity, with measured maximum uptake of up to 5.27 wt.% at 298 K and 3.5 MPa and 2.05 wt.% at 77 K and 4.3 MPa respectively. The analysis of the obtained isotherm curves by Toth equation shows high grade of surface homogeneity of the samples. Total storage capacities were also estimated. For methane a maximum 41.6 v/v at 298 K and 3.5 MPa was found, while for hydrogen a maximum 15.8 g/L at 77 K and 4.3 MPa was calculated. (C) 2012 Elsevier Inc. All rights reserved. | en |
