Abstract
  • Platinum and palladium surfaces are utilized as catalytic surfaces in the chemical industry. Understanding how hydrogen atoms interact with the metal surfaces will allow for further advancement in this area. Specifically, the interaction of hydrogen on the surface and subsurface of these metals was investigated using density functional theory calculations through Python scripts and the VASP software. The tests concluded that the hydrogen adsorption is favorable on the surface of both metals, but only on the subsurface of palladium. In addition, when more than one atom of hydrogen was introduced to the metal, the two hydrogen atoms demonstrated repulsive effects on one another.
  • Key Words: Platinum, Palladium, catalytic surfaces, hydrogen atom
