Adsorption and Absorption Energies of Hydrogen with Palladium

The Journal of Physical Chemistry C, 2022
Thermal recombinative desorption rates of HD on Pd(111) and Pd(332) are reported from transient kinetic experiments performed between 523 and 1023 K. A detailed kinetic model accurately describes the competition between recombination of surface-adsorbed hydrogen and deuterium atoms and their diffusion into the bulk.
