中文摘要	La/sub 0.9/Cu/sub 0.1/MnO/sub 3/ and LaCoO/sub 3/ catalysts were synthesized by amorphous complexing method. Platinum nanoparticles supported by these composite oxide catalysts were prepared by using colloid deposition process. The structure, morphology, and Pt valence of the catalysts were characterized by transmission electron microscopy (TEM), X-ray diffraction (XRD), and X-ray photoelectron spectroscopy (XPS); and the cataluminescence (CTL) response of CO over the catalysts was investigated. Because of the agglomeration of Pt nanoparticles at the surface of La/sub 0.9/Cu/sub 0.1/MnO/sub 3/ catalyst, its cataluminescence spectra displayed a peak splitting, but the Pt/LaCoO/sub 3/ system, where Pt nanoparticles dispersed well at its surface, did not exhibit the phenomenon. We can use the cataluminescence spectra of CO to determine the dispersed state of noble metal nanoparticles at the surface of supports.
