| 제목 | Evaluation of hydrogenation properties on MgHx-V2O5 composites by mechanical alloying |
| 초록 | Hydrogen has a high potential to be a renewable susstitue for fossil fuels, because of its high gravimetirc energy dnesity and environement friendliness. In particular, Magnesium have attracted much interest since their hydrogen capacity exceeds that of known metal hydrides. One of the approaches to improve the kinetic is addition of metal oxide. In this paper, We tried to improve the hydrogen absorption/desorption properties of Mg. The effect of V2O5 concentration on the kinetics of the Mg hydrogen absorption reaction was investigated. MgHX-V2O5 composites have been synthesized by hydrogen induced mechanical alloying. The powder synthesized was characterized by XRD, SEM and simultaneous TG, DSC analysis. The hydrogenation behaviors were evaluated by using a sievert's type automatic PCT apparatus. Absorption and desorption kinetics of Mg catalyzed with 5, 10mass% V2O5 are determined at 423, 473, 523, 573, 623K.
