Graphic abstract: Single-atom alloy Pd<sub>1</sub>Ag<sub>10</sub>/Al<sub>2</sub>O<sub>3</sub> catalyst: Effect of CO-induced Pd surface segregation on the structure and catalytic performance in the hydrogenation of C<sub>2</sub>H<sub>2</sub>

Abstract: The effective surface concentration of Pd₁ sites composed of individual palladium atoms isolated from each other by Ag atoms in the Pd₁Ag₁₀/Al₂O₃ single-atom alloy (SAA) catalyst can be significantly enhanced by the adsorption-induced surface segregation upon a special pretreatment of the catalyst in a CO-containing atmosphere at 200 °C. The catalyst activity towards acetylene hydrogenation gets tripled without sacrificing selectivity for ethylene. The segregated surface of the catalyst is thus preserved under target reaction conditions.

Keywords: single-atom alloy catalyst, adsorption-induced segregation, CO adsorption, selective acetylene hydrogenation, Pd, DRIFTS, XPS.
