摘要：
The PdAg/a-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.
