In order to increase measurement throughput, a characterization scheme has been developed that accurately measures the hydrogen storage properties of materials in quantities ranging from 10 ng to 1 g. Initial identification of promising materials is realized by rapidly screening thin-film composition spread and thickness wedge samples using normalized IR emissivity imaging. The hydrogen storage...
We report a first-principle study of the tunable hydrogenation of endohedral metallofullerenes M@C60 and M2@C60, where M ) Li, Be, Mg, Ca, Al, and Sc. The interaction between the encapsulated metal atoms and the C60 cage leads to a tuning of the hydrogen binding in a desired manner as the hydrogenation proceeds. At lower H densities, when H atoms are too strongly bound to pure C60, the endohedr...
The Electrochemical Society Interface • Fall 2004 ydrogen storage is a crucial step for providing a ready supply of hydrogen fuel to an end use, such as a car, as it is considered by many to be the most technically challenging aspect of achieving a hydrogen-based economy. Current hydrogen storage materials or systems are still far short of meeting target goals set for either 2010 or 2015. Two k...
