On the enhancement of hydrogen uptake by IRMOF-8 composites with Pt/carbon catalyst

IRMOF-8 bridged and un-bridged composites with Pt on activated carbon catalyst were synthesized with the aim to reproduce the considerable enhancement of hydrogen storage at ambient temperature reported in literature. X-ray powder diffraction patterns, surface areas and pore volumes of the synthesized materials are comparable with the literature data. However, the hydrogen sorption isotherms at room temperature do not exhibit any significant enhancement of hydrogen uptake as compared to the pristine materials.

► IRMOF-8 synthesis and preparation of bridged and un-bridged composites with Pt/activated carbon.
► Surface area and pore volume from nitrogen adsorption.
► Catalyst activity test by isotopic exchange.
► Hydrogen uptake measurements at 298 K does not show significant enhancement.
