The present invention relates to a process and catalyst for the hydrogenation of olefin oxides such as propylene, such as propylene, to form olefin oxides such as propylene oxide. The method comprises contacting an olefin with oxygen under reaction conditions in the presence of hydrogen and hydrogen oxidation catalyst, the catalyst depositing a gold-ligand cluster complex on a support to form a catalyst precursor and then heating the catalyst precursor. And / or gold nanoparticles deposited on the nanoporous titanium-containing support prepared by chemical treatment to form a hydrogen oxidation catalyst composition. These hydrogen oxidation catalysts exhibit stabilized catalytic activity, increased lifetime and improved hydrogen efficiency. |
