Selective butadiene hydrogenation by Pd nanoparticles deposed onto nano-sized oxide supports by CVD of Pd-hexafluoroacetylacetonate

► Platinum hexafluoroacetylacetonate as catalyst precursor. ► Palladium nanoparticles supported on TiO2, CeO2 and ZnO. ► Heterogeneous catalysts for selective butadiene hydrogenation to butene. ► Palladium nanoparticles supported on CeO2 show highest selectivity to butene.
