The invention is a liquid-phase process for epoxidizing an olefin with hydrogen and oxygen in the presence of a supported catalyst comprising palladium on niobium-containing support. The process exhibits good productivity and selectivity for olefin epoxidation with hydrogen, and oxygen. This is particularly surprising because typical palladium-containing epoxidation catalysts require the presence of a titanium zeolite.
