FABRICATION AND HYDROGEN STORAGE PROPERTY OF Mg-3Ni-2MnO2-nCNTS NANOCOMPOSITES

摘要：

Mg-3Ni-2MnO2 hydrogen storage nanocomposites added with different composition (1％～4％) carbon nanotubes (CNTs) were prepared by mechanical milling under the atmosphere of hydrogen. Different mechanical milling process parameter has been discussed in this paper. Study on hydrogen storage ability of Mg-3Ni-2MnO2-nCNTs with different composition carbon nanotubes has been carried out. The result show that Mg-3Ni-2MnO2-nCNTs excellent heat conductivity and good hydrogen storage (more than 6％vol) ability, the CNTs improve the mass transfer and heat transfer properties of the Mg-3Ni-2MnO2, thus enhancing the kinetic property of hydrogen absorption and desorption of the hydrogen storage nanocomposites, and raising the hydrogen storage capacity. Due to the addition of the carbon nanotubes, the milling stress in the process of preparing the Mg-based namocomposites is reduced, the components can be closely bonded easily, and the additives can play better catalytic roles enhancing the kinetic property of hydrogen absorption and desorption of the hydrogen storage nanocomposites, and raising the hydrogen storage capacity. Due to the addition of the carbon nanotubes, the milling stress in the process of preparing the Mg-based namocomposites is reduced, the components can be closely bonded easily, and the additives can play better catalytic roles.
