The near surface structural evolution in dehydrogenation process of air exposed Pd coated Mg nanoblades was characterized in situ from room temperature to 573 K using reflection high energy electron diffraction RHEED . The evolved normalized diffraction intensity and the full width at half maximum of diffraction peaks have been correlated with the growth of crystal and the change in crystal siz...

Electrical generation from hydrogen, the element with higher energy density per unit mass, requires appropriated materials that can be used in its storage [1]. Palladium, with a high capacity to dissociate, absorb and desorb gaseous hydrogen, has been widely used for hydrogen storage [2], in separation membranes [3] and catalytic hydrogenation [4]. The present DFT calculations on clusters model...
