Hydrogen storage material with intermediate bond strength and process for making the same
Provided herein are materials that can achieve up to 14% hydrogen absorption by weight in ambient conditions, which is a marked improvement over the hydrogen absorption values found in the prior art. Further provided are experimental conditions necessary to produce these materials. In order to produce the hydrogen storage material, a transition metal (or Lithium) is vaporized in a pi bond gas in conditions that permit only a few bonding collisions to occur between the vaporized transition metal atoms and pi bond gas molecules before the resulting bonded material is collected.
