摘要：

Pore size matters: The heat of adsorption for hydrogen is determined over a wide range of surface coverages for activated carbon and several metal-organic frameworks. Heat determination is based on hydrogen adsorption measurements performed at temperatures between 77 and 296 K (see figure, BTC = benzene-1,3,5-tricarboxylate). The materials with smaller cavities show a higher heat of adsorption for hydrogen. (Figure Presented) © 2008 Wiley-VCH Verlag GmbH & Co. KGaA.
