a Representative TEM images of Pd NSs. b High-resolution high-angle annular dark-field (HAADF) STEM image of PdCu@Cu2O (Cu/Pd=1). c STEM-EDS elemental mapping of PdCu@Cu2O (Cu/Pd=1). d The first derivatives of Cu K-edge XANES of PdCu@Cu2O with different Cu/Pd ratio and references. e Catalytic performance of semi-hydrogenation of PhC≡CH on PdCu@Cu2O with different Cu/Pd ratios. Reaction conditions: 10 mL ethanol; 2 μmol Pd; 4 mmol PhC≡CH (1:2,000); T = 303 K; H2 pressure = 0.1 MPa (PhC≡CH was introduced before H2).
