Hydrogen Absorption/Desorption in Palladium and Metal Hydrides
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...
متن کاملPreparation and Hydrogen Absorption/Desorption of Nanoporous Palladium Thin Films
Nanoporous Pd (np-Pd) was prepared by co-sputtering Pd-Ni alloy films onto Si substrates, followed by chemical dealloying with sulfuric acid. X-ray diffractometry and chemical analysis were used to track the extent of dealloying. The np-Pd structure was changed from particle-like to sponge-like by diluting the sulfuric acid etchant. Using suitable precursor alloy composition and dealloying cond...
متن کاملEFFECT OF MISH METAL TYPE ON THE MICROSTRUCTURE AND ABSORPTION/DESORPTION CHARACTERISTICS OF MMNI5 HYDROGEN STORAGE ALLOY
In this article, the effects of Pr and Nd were investigated on the microstructure and absorption/desorption characteristics of MmNi5 hydrogen storage alloy. The alloys were prepared in Vacuum induction furnace and the microstructures and phases were analyzed using scanning electron microscopy (SEM) equipped with energy dispersive X-ray analysis (EDS) and X-ray diffraction (XRD). Hydrogen absorp...
متن کاملHydrogen Absorption/Desorption Properties in the TiCrV Based Alloys
Three different Ti-based alloys with bcc structure and Laves phase were studied. The TiCr 1.1 V 0.9 , TiCr 1.1 V 0.45 Nb 0.45 and TiCr 1.1 V 0.9 + 4%Zr 7 Ni 10 alloys were melted in arc furnace under argon atmosphere. The hydrogen absorption capacity was measured by using aparatus type Sievert’s. Crystal structures, and the lattice parameters were determined by using X-ray diffraction, XRD. Mic...
متن کاملKinetics of hydrogen absorption in transition metals and subsurface bonding
We have modified the kinetic equations for the absorption of hydrogen in transition metals to include the effects of strong subsurface bonding. The new equations show that the subsurface, self-trapped hydrogen acts as a valve for the admission of hydrogen into the bulk. The explanation for a number of experimental facts, not well understood before, neatly follows. Discrepancies between theory a...
