HYDROGEN STORAGE PROPERTY OF Mg-Ni-TiO2-CNTs COMPOSITES

摘要：

In this paper, the nanocrystalling composite Mg-Ni-TiO2-CNTs was made by mechanical ball milling under hydrogen pressure of 5.0×10 5Pa, The hydrogen storage properties and operation temperatures were investigated. It was found that the composite can absorb 7.5wt.％ hydrogen in 60s under 5.0×10 5Pa hydrogen pressure and desorb 6.5wt％ hydrogen in 600s at 260℃ under 5.0×10 5Pa hydrogen pressure. The composite has very high absorption, hydrogen capacity and remarkable kinetic properties in hydriding /dehydeiding process. TiO2, Ni and CNTs were used as additive to improve the hydrogen storage performance. They can be utilized as an effective catalyst to improve hydriding/dehydriding performance of hydrogen storage material and lead to pronounced enhancement on the hydrogen storage property of Mg. The results showed that the composite has potential application in the future.
