| 英文摘要 | for li3alh6 prepared by mechanical milling method, the dissociation reaction enthalpy and activation energy are calculated to be 22.1 kj mol(-1) h-2 and 133.7 +/- 2.7 kj moll, respectively. the dehydrogenation performance of li3alh6 is greatly enhanced by tif3 additive, especially in the kinetic behaviors. for the li3alh6 + 10 mol% tif3 sample, the starting temperature of dehydrogenation is obviously decreased by 60 degrees c from that of pure li3alh6 (190 degrees c), and 3.0 wt.% h-2 may be released within 1000 s at 120 degrees c under an initial vacuum. with the amount of tif3 increasing, the starting temperature decreases and the kinetics improves due to the decrease in the activation energy. the x-ray diffraction (xrd) together with thermogravimetric analysis (tga) results show that there are three mechanochemical reactions involved during milling: i) li3alh6 + tif3 -> 3 lif + al + ti + 3h(2), ii) ti + h-2 tih2, iii) 3 al + ti -> al3ti. the in-situ formed ti species (tih2 and al3ti) co-catalyze the thermal dehydrogenation of li3alh6.
