The present invention relates to a process for the preparation of hydrogen peroxide from oxygen or oxygen-delivering substances and hydrogen or hydrogen-delivering substances in the presence of at least one catalyst containing a metal-organic framework material, wherein said framework material comprises pores and a metal ion and an at least bidentate organic compound, said bidentate organic compound being coordinately bound to the metal ion. The invention further relates to a novel material consisting of said metal organic framework material wherein the material is brought in contact with at least one additional metal.
