英文摘要: The dehydrogenation performances of as-received, ball-milled and different amounts of TiF3 doped LiAlH4 were investigated by X-ray diffraction(XRD), Fourier transformed infrared spectrometer(ETIR) and thermogravimetry(TG) measurements. It was found that LiAlH4 decomposes a little during ball milling in the presence of TiF3. TiF3 has dramatically catalyzed the dehydrogenation of LiAlH4. With increasing amount of TiF,, the initial temperature of dehydrogenation decreases to some extent, hut it sacrifices the dehydrogenation amount at great cost. 2% (molar fraction) TiF3-doped LiAlH4 begins to release H-2 at 80 degrees C, 70 degrees C lower than as-received LiAlH4, and can release as much as 6.6% (mass fraction) H-2.
