Recombination of hydrogen atoms on the surface of alkali metal salts

Abstract

Hydrogen atom recombination coefficients γ_H were measured for polycrystalline NaCl, KCl, NH₄Cl, Na₂SO₄, Na₃PO₄, and Na₂CO₃ samples in the temperature range 295-600 K. The influence of adsorbed H₂O, O₂, and other molecules on the catalytic activity of the samples was studied. A model of recombination of hydrogen atoms taking into account the presence of a layer of adsorbed molecules and the possibility of transfer of excess recombination energy to these molecules was suggested. The concentration of hydrogen atoms and molecules in the gas phase had a strong influence on γ_H.
