The dehydrogenation properties of LiAlH4 doped with Y2O3 were investigated by PCT (Pressure-Composition-Temperature) equipment. The results show that with the increase of amount of Y2O3, the dehydrogenation amount of LiAlH4 increases, however, when the doping amount reaches a certain value, the hydrogen release amount decreases with the increase of doping amount. Compared to the LiAlH4 sample, the dehydrogenation starting time of the samples doped with Y2O3 is significantly brought forward. In addition, it can be found that the dehydrogenation rates of all the doped samples are higher than that of the original sample. The change trends of the dehydrogenation rates of all the doped samples are similar in the whole dehydrogenation process, namely, with the extension of time, the dehydrogenation rates increase firstly, and then decrease gradually.
