Surface Adsorption to Bulk Storage: Integrating Experimental and Theoretical Insights into Hydrogen Behavior on Palladium
This study integrates experimental characterization and density functional theory to demonstrate that hydrogen uptake in both palladium foils and nanowires follows a unified mechanism where barrierless, exergonic migration from the surface to the bulk facilitates robust diffusion with a 0.123 eV barrier, regardless of the material's morphology.
