Adding a small amount of nanocrystalline TiO2@C （TiO2 supported on nano- porous carbon） composite dramatically decreases the operating temperatures and improves the reaction kinetics for hydrogen storage in NaAlH4. The nano- crystalline TiO2@C composite synthesized at 900 ℃ （referred as TiO2@C-900） exhibits superior catalytic activity to other catalyst-containing samples. The onset dehydrogenation temperature of the TiO2@C-900-containing sample is lowered to 90 ℃; this is 65 ℃ lower than that of the pristine sample. The dehydrogenated sample is completely hydrogenated at 115 ℃ and 100 bar of hydrogen pressure with a hydrogen capacity of 4.5 wt.%. Structural analyses reveal that the Ti undergoes a reduction process of Ti^4＋→Ti^3＋→Ti^2＋→Ti during the ball milling and heating processes, and further converts to Ti hydrides or forms Ti-Al species after rehydrogenation. The catalytic activities of Ti-based catalytic species decrease in the order Al-Ti-species 〉 TiH0.71 〉 TiH2 〉 TiO2. This understanding guides further improvement in hydrogen storage properties of metal alanates using nanocrvstalline transition metal-based additives.

A porous Co3O4with a particle size of 1–3 μm was successfully prepared by heating Co-based metal organic frameworks MOF-74（Co） up to 500 °C in air atmospheric conditions. The as-prepared porous Co3O4significantly reduced the dehydrogenation temperatures of the LiBH4-2LiNH2system and improved the purity of the released hydrogen. The LiBH4-2LiNH2-0.05/3Co3O4sample started to release hydrogen at 140 °C and released hydrogen levels of approximately 9.7 wt% at 225 °C. The end temperature for hydrogen release was lowered by 125 °C relative to that of the pristine sample. Structural analyses revealed that the as-prepared porous Co3O4is in-situ reduced to metallic Co, which functions as an active catalyst, reducing the kinetic barriers and lowering the dehydrogenation temperatures of the LiBH4-2LiNH2system. More importantly, the porous Co3O4-containing sample exhibited partially improved reversibility for hydrogen storage in the LiBH4-2LiNH2system.

Critical limitations in applying MgH_(2) as a hydrogen-storage medium include the high H_(2) desorption temperature and slow reaction *** this study,we synthesized hierarchical porous TiNb_(2)O_(7) spheres in micrometer scale built with 20-50 nm nanospheres,which showed stable activity to catalyze hydrogen storage in MgH_(2) as *** addition of 7 wt.%TiNb_(2)O_(7) in MgH_(2) reduced the dehydrogenation onset temperature from 300 to 177℃.At 250℃,approximately 5.5 wt.%H_(2) was rapidly released in 10 *** uptake was detected even at room temperature under 50 bar hydrogen;4.5 wt.%H_(2) was absorbed in 3 min at 150℃,exhibiting a superior low-temperature hydrogenation ***,nearly constant capacity was observed from the second cycle onward,demonstrating stable *** the ball milling and initial de/hydrogenation process,the high-valent Ti and Nb of TiNb_(2)O_(7) were reduced to the lower-valent species or even zero-valent metal,which in situ created multivalent multielement catalytic surroundings.A strong synergistic effect was obtained for hybrid oxides of Nb and Ti by density functional theory(DFT)calculations,which largely weakens the Mg-H bonding and results in a large reduction in kinetic barriers for hydrogen storage reactions of MgH_(2).Our findings may guide the further design and development of high-performance complex catalysts for the reversible hydrogen storage of hydrides.
