Abstract

In this paper, the structural and hydrogenation characteristics of TiF₃-doped Zintl phase alloy SrAl₂ were studied by X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS) and hydrogenation measurements. The results show that the hydrogenation kinetics of the Zintl phase alloy SrAl₂ is improved greatly after doping with TiF₃. By adjusting the doping amount and ball milling time, the optimal doping conditions were obtained. The catalytic mechanism of TiF₃ for the hydrogenation of SrAl₂ was also investigated. SrAl₂ does not react with TiF₃ during the ball milling process. However, it reacts with TiF₃ to form SrAl₂H₂, SrF₂, SrAl₄ and Ti during the hydrogenation process, among which Ti plays an important role in the hydrogenation kinetics of SrAl₂.
