Atoms and Nanoparticles of Transition Metals as Catalysts for Hydrogen Desorption from Magnesium Hydride
Figure 12
Dehydrogenated fraction versus time at various temperatures for the Mg sample with mixed Fe-Zr additives at 623 K, 613 K, 603 K, 593 K, 583 K, and 573 K. In the insert we present the Arrhenius plot of the desorption rate constant k: the straight line is the least square fit.
