Abstract: This invention provides a process for the activation of a metallic palladium containing catalyst which is useful for the direct oxidation of hydrogen by oxygen to hydrogen peroxide, by treating the catalyst with an oxidising agent in order to at least partially oxidise the metallic palladium contained in the catalyst to palladium (TT) oxide. The selectivity and yield of the catalyst for hydrogen peroxide are observed to increase substantially and the hydrogen peroxide decomposition activity of the catalyst is drastically reduced.
