Hydrogen adsorption on PdGa(110): A DFT study
H and Pd bonding is analyzed using density functional theory (DFT) calculations. Changes in the electronic structure of PdGa(110) surface upon the introduction of one or two hydrogen atoms are addressed. H locates only on Pd atop geometry and no interaction with Ga is detected. The Pd-Pd bond streng...

| Sumario: | H and Pd bonding is analyzed using density functional theory (DFT) calculations. Changes in the electronic structure of PdGa(110) surface upon the introduction of one or two hydrogen atoms are addressed. H locates only on Pd atop geometry and no interaction with Ga is detected. The Pd-Pd bond strength decreases as the new Pd-H bond is formed. The effect of H is limited to its first Pd neighbor. An analysis of orbital interaction reveals that Pd-H bonding mainly involves Pd 5s and H 1s orbitals with less participation of Pd 5p and 4d orbitals. © 2012 American Chemical Society. |
