Abstract
The PdAg/α-Al 2 O 3 catalyst with an egg-shell distribution of single-atom alloy (SAA) Pd 1 Ag nanoparticles was obtained using the complex PdAg 2 (OAc) 4 (HOAc) 4 as a precursor and characterized by FESEM-EDS, XPS, and DRIFTS CO analysis. The egg-shell Pd 1 Ag SAA catalyst demonstrated superior selectivity in the hydrogenation of acetylene in acetylene–ethylene feed.
