MgHx-Sc2O3 복합재료의 수소화 특성 = Hydrogenation Properties on MgHx-Sc2O3 Composites by Mechanical Alloying

다국어 초록 (Multilingual Abstract)

Hydrogen energy applications have recognized clean materials and high energy carrier. Accordingly, Hydrogen energy applies for fuel cell by Mg and Mg-based materials. Mg and Mg-based materials are lightweight and low cost materials with high hydrogen storage capacity. However, commercial applications of the Mg hydride are currently hinder by its high absorption/desorption temperature, and very slow reaction kinetics. Therefore one of the most methods to improve kinetics focused on addition transition metal oxide. Addition to transition metal oxide in MgHx powder produce MgHx-metal oxide composition by mechanical alloy and it analyze XRD, EDS, TG/DSC, SEM, and PCT. This report considers kinetics by transition metal oxide rate and Hydrogen pressure. In this research, we can see behavior of hydriding/dehydriding profiles by addition catalyst (transition metal oxide). Results of PCI make a excellent showing MgHx-5wt.% Sc2O3 at 623K, MgHx-10wt.% Sc2O3 at 573K.
