摘要：

A catalyst containing chromium oxide particles on the surface of palladium nanoparticles is synthesized for the first time using a redox technique for reduction with adsorbed hydrogen. The low-temperature reduction of chromium oxide and formation of palladium hydride is reported for the first time in such catalyst. A considerable difference between its catalytic properties in the selective hydrogenation of phenylacetylene and those of the initial palladium catalyst is shown.
