LiAlH4 doped with Ti and Fe additives have been studied by PCT experiment and X-ray diffraction. Doping with Ti and Fe significantly decreased the amount, the temperature and the rate of hydrogen release. Doping with Fe induced the largest decrease in the temperature; however, the amount of hydrogen release was significantly higher than that of the samples doped with Ti. Compared with the sample doped with 5 mol% Ti, the sample doped with 5 mol% Fe presented a lower dehydrogenation rate in the first step. The result obtained by XRD patterns for LiAlH4 doped with 5mol% Fe and LiAlH4 doped with 1, 3 and 5 mol% Ti heated at 250 °C showed that doping additives did not cause any structure change. No Ti and Fe or the secondary Ti and Fe-containing phases were found.
