Hydrogen Technology: H_2 Storage and Release

摘要

A promising hydrogen-storage material was synthesized by the ball-milling technique on the basis of complex investigation of Zr ― H and Zr ― H ―graphite systems. Combination of micro- and nano-sized Zr-containing fragments embedded in a carbon ribbon-like matrix affords the stability of the material. Zr-containing fragments can be transformed in ZrH_2-containing fragments of the same morphology. The bulk hydrogen can be completely removed from and introduced into these fragments at 420 ― 430℃.
