Claims12
A method of storing hydrogen comprising:
- contacting gaseous hydrogen with an imide represented by Mc(NH)−2c/2, where M represents a cationic species of at least one member selected from group consisting of Li, Mg, Na, B, Al, Be, Zn, and mixtures thereof and c represents an average valence state of M, wherein said imide forms at least two distinct compounds different from said imide upon reaction with hydrogen.
