抄録

Catalytic CO oxidation over Pd(111) and Pd₇₀Au₃₀(111) surfaces was investigated by in situ spectroscopic observations to understand the alloying effect. The reaction behaviour on Pd₇₀Au₃₀(111) is greatly different from that on Pd(111). Pd monomer and dimer ensembles can act as active centers, whereas triangular-shaped trimers and larger ensembles are inactive.
