| 摘 要： | 采用溶胶－凝胶法和溶胶－凝胶＋浸渍法两种方法制备了CuO-Ce0.7Zr0.3O2催化剂，并对催化剂进行了XRD、Raman等表征，考察了催化荆的CO氧化性能。研究结果表明，溶胶－凝胶＋浸渍法制备的CuO/Ce0.7Zr0.3O2催化荆CO氧化活性明显高于溶胶－凝胶法制备的CuO-Ce0.7Zr0.3O2催化剂的性能，CuO-Ce0.7Zr0.3O2催化剂表面CuO分散度高．从而提高催化活性。

| Abstract: | CuO-Ce0.7Zr0.3O2 catalysts were prepared by two sol-gel methods and tested for CO oxidation.H2 temperature programmed reduction results revealed that the CuO particles were more finely dispersed in the catalyst prepared by sol-gel method.Raman spectra of the catalysts indicated that more oxygen vacancies were formed in the catalyst prepared by sol-gel method than that by sol-gel impregnation method.These two facts contributed to the higher activity for the sol-gel The catalyst prepared by sol-gel method was... |
