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。
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.
