Hydrogen storage in metal-organic frameworks

Hydrogen storage in microporous metal-organic frameworks.

Metal-organic framework-5 (MOF-5) of composition Zn4O(BDC)3 (BDC = 1,4-benzenedicarboxylate) with a cubic three-dimensional extended porous structure adsorbed hydrogen up to 4.5 weight percent (17.2 hydrogen molecules per formula unit) at 78 kelvin and 1.0 weight percent at room temperature and pressure of 20 bar. Inelastic neutron scattering spectroscopy of the rotational transitions of the ad...

The current status of hydrogen storage in metal–organic frameworks†

The rapid consumption of petroleum deposits and the escalating air pollution problems caused by burning fossil fuels have driven the global research community to look for cleaner and renewable energy resources. Albeit not a primary energy source, hydrogen is an ideal energy carrier. It almost triples the gravimetric heat of combustion of gasoline (120 MJ kg 1 vs. 44.5 MJ kg ). More importantly,...

Strategies for hydrogen storage in metal--organic frameworks.

Increased attention is being focused on metal-organic frameworks as candidates for hydrogen storage materials. This is a result of their many favorable attributes, such as high porosity, reproducible and facile syntheses, amenability to scale-up, and chemical modification for targeting desired properties. A discussion of several strategies aimed at improving hydrogen uptake in these materials i...
