英文摘要We used a dielectric barrier discharge (DBD) plasma technique to eliminate the protective ligand of ZnAl-hydrotalcite-supported gold nanoclusters. We used X-ray powder diffraction, ultraviolet-visible spectrophotometry, thermogravimetric analysis, and high angle annular dark-field-scanning transmission electron microscopy characterization to show that the samples pretreated with/without DBD-plasma displayed different performances in CO oxidation. The enhanced activity was obtained on the plasma-treated samples, implying that the protective ligand was effectively removed via the plasma technique. The crystal structure of the plasma-treated samples changed markedly, suggesting that the plasma treatment could not only break the chemical bond between the gold and the protective agent but could also decompose the interlayer ions over the hydrotalcite support. The particle sizes of the gold after DBD-plasma treatment implied that it was a good way to control the size of the gold nanoparticles under mild conditions.
