Abstract: Single-atom Pd₁Cu_n/Al₂O₃ catalysts were studied in front-end acetylene hydrogenation. It was found that the selectivity to ethylene increases sharply as the Pd : Cu ratio changes from 1 : 1 to 1 : 10. Single-atom PdCu/Al₂O₃ catalysts demonstrate remarkable resistance to CO swings and retain high selectivity in its absence, which are crucial for industrial applications.

Keywords: acetylene hydrogenation, front-end, PdCu, single-atom catalyst, bimetallic alloy.
