英文摘要: Metals (Ni, Fe)-incorporated titanate nanotubes (M-TNT, M = Ni, Fe) with H2Ti3O7 structure were synthesized to destabilize the LiBH4 for hydrogen storage. The onset temperature of dehydrogenation was reduced to 100 degrees C for LiBH4 and M-TNT composite, which could release 4.5 wt % hydrogen at 120 degrees C and 11 wt % hydrogen at 260 degrees C from LiBH4. Our experiment results indicate that ball-milled LiBH4/Ni TNT sample has a better dehydrogenation performance than ball-milled LiBH4/Ni/H2Ti3O7 nanotube and ball-milled LiBH4/NiO/H2Ti3O7 nanotube samples. Furthermore, one finds that the release of poisoning species like BH3 and B2H6 could be inhibited by nanotube with H2Ti3O7 structure rather than that with anatase structure. The interactions between LiBH4 and different structure nanotubes are investigated by the first-principle calculation in the present work.
