Description
Technical field
The present invention relates to solid hydrogen storage material field, and in particular to a kind of Carbon foam load magnesium ambrose alloy composite hydrogen storage material and
Its preparation method.
Background technology
Hydrogen Energy is one of great strategy demand towards the country, in the evolution of Hydrogen Technology, and the storage of hydrogen is heavy to closing
The link wanted, solid-state hydrogen storage has been the focus and emphasis of domestic and international Hydrogen Energy research, coordinating metal hydride hydrogen storage and alloy hydrogen storage
It is main method.Coordinating metal hydride is usually by alkalies and alkaline earth [AlH4]-、[NH2]-、[BH4]-wait hydrogenation
Thing anion is constituted, and maximum difference is exactly that hydrogen storage content is big with alloy, needs higher suction hydrogen discharging temperature, circular response invertibity compared with
Difference, coordinating metal hydride puts hydrogen process, and not a step is completed, also more difficult control in actual applications.Hydrogen bearing alloy is before relatively having
The hydrogen storage material on way, so far, hydrogen bearing alloy system include：Magnesium system, zirconium system, titanium system, Rare Earth etc., will reach actual answer
With, it is necessary to possess several requirements：(1) anti-poisoning, the hydrogen storage of high selectivity；(2) hydrogen storage speed is fast；(3) there should be high hydrogen storage
Capacity；(3) can be under the conditions of higher than hydrogen storage temperature, quick heating desorption discharges pure hydrogen；(5) polycyclic hydrogen storage, release hydrogen are anti-
The high activity and stability used again.Hydrogen molecule is diffused into the surface of hydrogen storage material, is catalyzed by surface metal, and H-H is covalent
Key is broken, and hydrogen atom is attached to the surface of hydrogen storage metal alloy, and is spread with the state of atom into metal lattice, forms metal
The solid solution (α phases) of atom and hydrogen atom, with saturation of the hydrogen atom in lattice, metallic atom reacts with hydrogen atom,
Phase transformation generation metal hydride β phases).Hydrogen bearing alloy is typically made up of two parts：Part A and part B.Part A has certain with H
Affinity interaction, it determines hydrogen storage content；Part B then plays adjustment pressure, and the effect such as hydrogen power is put in suction.
Magnesium microalloying is a most promising class hydrogen storage material, such as：Mg2Co、Mg26Cu、MgNiCuLax、
MgH2- 5%Mg, MgH-5%V, MgNiH4、Mg2FeH5Preferable hydrogen sucking function is shown, because Mg's cheap, density
Small, and hydrogen storage content is high, theoretical hydrogen storage content can reach 7.6wt%, but inhale hydrogen and slower, easily poisoning, to meet of releasing hydrogen discharging rate
Practical application, will be often modified, and conventional method of modifying is nanosizing first, because particle diameter reduces, and specific surface area increase is led
Hydrogen atom is caused to be more prone to spread on hydrogen bearing alloy surface, penetrate into material internal, while shortening hydrogen atom through hydride
Zeng Changcheng spreads, so that improving its suction puts hydrogen power.Tong Liu et al. in Journal of Hydrogen Energy,
2014,39 (32)：18273-18279 researchs cause Mg particle diameter to be reduced to 200nm using hydrogen plasma arc process (HPMR),
LaNi5Particle diameter be reduced to 25nm, then by these particles with Mg-5%LaNi5Ratio mixing, improve suction hydrogen desorption kineticses
Performance, but preparation process is complicated, and cost is very high, the hydridization of this particle not of the same race, makees to improving the anti-impurity performance of material hydrogen storage
With also less, the easy poisoning and deactivation of hydrogen storage material, service life is not high.Hu Xiuying etc. is in functional material the 3rd phase volume 39 in 2008
The page number：High-energy ball milling reaction method in 424-525, research hydrogen atmosphere, is prepared for magnesium carbon composite hydrogen storage material, when have studied ball milling
Between influence to material particle size, crystal structure and hydrogen discharging performance because using common carbon powder material, hydrogen storage property does not have greatly
The raising of amplitude.Carbon-based material includes：The storage of activated carbon, Carbon foam, Graphite Nano Fiber, carbon nano-fiber and CNT etc.
Hydrogen capacity is extremely limited, and preparation process includes multiple steps, and cost is very high.The good solid hydrogen storage material of design has to
Ensure its mass transfer, reaction and absorption property good to hydrogen, internal good heat transfer is most important, usual solid storage
Heat transference efficiency between thermal conductivity factor and the alloy powder bed and reactor outer wall of hydrogen material is generally very low.Therefore, make
It is frequently necessary to apply some heat transfer enhancement technologies during with metal hydrogen-absorbing material hydrogen storage.However, the hydrogen storage process occurred at present is strong
Change heat transfer technology Shortcomings：Efficiency is low, cost is high or is difficult to.
