The hydrogen oxidation reaction on polycrystalline silver was studied. It has been shown that only adsorbed at the surface oxygen species interact with hydrogen. Oxygen atoms located into the metallic silver bulk not participate in the reaction. The interaction of hydrogen with surface oxygen occurs in two stages: the fast one and the slow one. The rate-determining step of the reaction is revealed, which is the interaction of a hydrogen molecule with a surface hydroxyl group giving a water molecule and adsorbed hydrogen atom. The adsorbed hydrogen atom rapidly interacts with the second surface hydroxyl group according to the following equation. The results obtained in this study show a mechanistic similarity between the catalytic oxidation of hydrogen on silver and the branched chain reaction of hydrogen combustion.
