Ball milling and compression effects on hydrogen adsorption by MOF: Pt/carbon mixtures
Microporous and Mesoporous Materials, 2015•Elsevier
The effect of ball milling energy on hydrogen adsorption on metal–organic framework: Pt/AC
mixtures (HKUST-1: Pt/AC, AC–activated carbon) is reported. Experiments within a wide
range of ball milling energies show a decrease of hydrogen adsorption with the increasing
energy transferred to the sample. The results correlate well with the decrease of surface
area and pore volume. The infrared spectra reveal that the mechanical energy transferred to
the sample induces modifications in the metal coordination environment, the most compliant …

Abstract
The effect of ball milling energy on hydrogen adsorption on metal–organic framework:Pt/AC mixtures (HKUST-1:Pt/AC, AC – activated carbon) is reported. Experiments within a wide range of ball milling energies show a decrease of hydrogen adsorption with the increasing energy transferred to the sample. The results correlate well with the decrease of surface area and pore volume. The infrared spectra reveal that the mechanical energy transferred to the sample induces modifications in the metal coordination environment, the most compliant to compression part in the structure of the metal–organic frameworks. A comparison with the results on compressed pellets of the mixture reveals that both the ball milling and compression lead to similar effects, originating in mechanical energy transferred to the sample.
