Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>In this study, LiTi₂O₄ was synthesized as a possible catalyst in the Li‐N‐H system. The properties of hydrogen desorption in the Li‐N‐H system with a homogeneous catalyst have been investigated. The X‐ray diffraction and X‐ray photoelectron spectroscopy results indicated that the single phase of LiTi₂O₄ was successfully synthesized and it was stable in the sample after high energy ball‐milling and heat treatment. LiTi₂O₄ exhibited a catalytic effect in the Li‐N‐H system according to the thermogravimetry differential thermal analysis results. During dehydrogenation, a storage capacity of 5.7 wt % was obtained under moderate temperature. A sharp peak of thermal gas desorption mass spectrometry curve occurred at 227 °C. Furthermore, the catalytic mechanism of LiTi₂O₄ in the Li‐N‐H system was discussed in accordance with the experimental results.</p> </abstract>
