Abstract

A herein proposed PdAu/Al2O3 egg-shell catalyst for selective acetylene hydrogenation combines two factors to provide perfect performance: isolation of Pd1 active sites by Au and an egg-shell distribution of the active phase across the catalyst pellets. The PdAu/Al2O3 catalyst exhibits high acetylene hydrogenation activity at the level of Pd-catalysts and high intrinsic ethylene selectivity of Au-catalysts.
