The formation of a PdCu alloy with an fcc structure in 1% Pd–1.2% Cu2 /Al2O3 (as evidenced by XRD and EXAFS data) significantly improves catalyst selectivity in the semihydrogenation of internal and terminal alkynes, which makes 1% Pd–1.2% Cu2 /Al2O3 a promising alternative to the commercial Lindlar catalyst.
