The performance of Pt/Al2O3 catalysts with CeO2-ZrO2 in difference ways was studied by NIR-FT-Raman, BET, H2 chemisorption, XRD. It shows that the dispersion of Pt on Al2O3 is improved with the increasing of dispersion of CeO2-ZrO2 on the surface of Al2O3, owing to the strong interacting between CeO2-ZrO2 and Pt. And adding with salts is priority.
通过近红外傅里叶变换拉曼光谱、比表面积测定（BET）、氢气化学吸附、X射线衍射（XRD）等方法研究了不同方式制备的CeO₂-ZrO₂修饰的Pt/Al₂O₃催化剂的性能。结果表明，由于CeO₂-ZrO₂与Pt之间的强相互作用，随着CeO₂-ZrO₂在Al₂O₃表面分散度的增加，Pt在Al₂O₃上的分散度得到提高。并且优先添加盐类。
