摘要：

Pt-Mo bimetallic clusters were prepared by vapor deposition and subsequent reduction of Mo(CO)//6 on Pt clusters contained in Y zeolite. The structure of these clusters was investigated by anomalous wide-angale X-ray scattering and X-ray absorption spectroscopy. The clusters have an atomic structure similar to that of bulk Pt, with Mo deposited epitaxially on the Pt clusters. Reduction at 573 K in dihydrogen was insufficient to completely reduce Mo to its zerovalent state.
