Hydrogen adsorption properties of well-known MOF-5 were studied at near ambient temperature and hydrogen pressures up to 120 bar. Pristine material was doped with Pt catalysts supported on activated carbon (AC) using two previously described procedures: physical mixture of a catalyst with MOF-5 and “bridging” procedure (MOF-5 and catalyst particles connected via carbon bridges) MOF-5. The maximum hydrogen adsorption measured on doped MOF-5 was 0.43 wt.%. These values are on the same level or even less than for catalyst free MOF-5 material. Therefore, doping of MOF-5 material with Pt catalyst has not resulted in increase of hydrogen storage value. Hydrogen adsorption for the samples with added catalyst showed correlation with BET surface area, exhibited isotherms typical for physisorption and no features which could be assigned to spillover effect.
