摘要
Metal atoms of Pd and Cu produced by coevaporation in a metal atom reactor,was solvated at low temperature. These solvated metal atoms,were immobillized in. the polymer pore structure for preparing Pd-Cu bimetallic cluster catalyst.XPS measurements sbowed that both Pd and Cu,were in a zero-valent state. TEM and XRD resulta indicated that the Pd-Cu cluster particles,were very small. Catalytic tests. showed that these catalysts are very active for 4-methyl-3-penten-2-one hydrogenation.
