摘要：Promoting the activation of hydrogenation on metal oxide catalysts is crucial but challenging for designing highly efficient heterogeneous metal oxide catalysts. Here, highly dispersed Pd nanoclusters were loaded onto CeO2 surface by incipient-wetness impregnation aiming to enhance the activation of hydrogen and hydroge-nation performance of CeO2. Detailed characterizations, including X-ray photoelectron spectroscopy, Raman and H-2/D-2 isotopic exchange experiments, revealed that the highly dispersed Pd on CeO2 increased the number of oxygen vacancies and thus hydrogen activation. As expected, the Pd/CeO(2 )catalyst delivered remarkably pro-moted hydrogenation activity compared to the pristine CeO2 catalyst.
