Abstract: Different experimental methods for the determination of metal dispersion on supported metal catalyst are introduced and compared，including static chemical absorption，dynamic chemical absorption，X-ray photoelectron spectroscopy，X-ray diffraction（XRD）and transmission electron microscopy（TEM）. At the same time，the suitable range，limitation and consistency with test results of these methods are discussed.

摘要： 简要介绍了几种催化剂表面金属分散度的测定方法，包括静态化学吸附法、动态化学吸附法、X射线光电子能谱法（XPS）、X射线衍射宽化法（XRD）和透射电子显微镜法（TEM）。同时，对这几种方法的适用范围、局限性和测定结果的一致性进行了讨论和总结。
