Abstract: The PdAg/α-Al₂O₃ catalyst with an egg-shell distribution of single-atom alloy (SAA) Pd₁Ag nanoparticles was obtained using the complex PdAg₂(OAc)₄(HOAc)₄ as a precursor and characterized by FESEM-EDS, XPS, and DRIFTS CO analysis. The egg-shell Pd₁Ag SAA catalyst demonstrated superior selectivity in the hydrogenation of acetylene in acetylene–ethylene feed.

Keywords: acetylene hydrogenation, egg-shell catalyst, single-atom alloy catalyst, PdAg alloy, heterobimetallic complex, catalyst characterization.
