A metal-oxide catalyst enhanced the desorption properties in complex metal hydrides

Abstract

In this study, LiTi₂O₄ was synthesized as a possible catalyst for complex metal hydrides. LiTi₂O₄ was stable in the sample after high-energy ball milling and heat treatment. LiTi₂O₄ exhibited a catalytic effect among the samples of MgH₂, LiAlH₄ and LiNH₂. The desorption kinetics and the purity of the desorbed hydrogen gas have been improved by doping LiTi₂O₄. Furthermore, the catalytic mechanism of LiTi₂O₄ was discussed in accordance with the experimental results.
