Abstract
The mixed powder method and covering method were adopted to prepare a composite that has hydrogen storage properties. In the experimental process, the alloy phases Mg2Ni and NiTi generated regularly; the penetration of the hydrogen atoms to the material was considered as the adsorption of the material to the hydrogen atoms; the original thermodynamic equation was edited; the crystal phases were optimized by adjusting the parameters about the material composition and gas concentration, so that providing advantageous channels of the hydrogen atoms in and out to improve the hydrogen storage properties. The results showed that integer multiples adjustment to trace element Ti could make hydrogen storage properties maximizing optimize and have controllability for the capacity and rate of hydrogen storage according to the newly editing equation. The innovation was to edit out equation that can improve the hydrogen storage properties through adjusting three parameters of trace element Ti, adsorption and penetration to find the most optimal condition improving the hydrogen storage properties.
Highlights
In recent years, the fossil fuel reserves are rapidly reduced lead to the existing reserves cant not meet the growing demand
The majority of the world energy currently comes from the fossil fuels, but the use of the fossil fuels can produce large amounts of the harmful substances, which causes a great threat to the environment
Low price, abundant resources and light quality Mg based material was adopted for two-way development of hydrogen storage material
Summary
The fossil fuel reserves are rapidly reduced lead to the existing reserves cant not meet the growing demand. According to a amount of H atoms, it was considered as the absorbed capacity of the material after penetrating to the material, the maximum permeate pressure reached 6500mOsm/Kg. The rate of hydrogen absorption and desorption showed the materials used in this experiment was hard to activate.
