摘要：Zeolite-supported metal catalysts have important applications in various catalytic reactions, but unveiling their atomic-scale structures is always a grand challenge. The developed transmission electron microscopy (TEM) characterization techniques, e.g., integrated differential-phase contrast (iDPC) scanning transmission electron microscopy (STEM) is emerging as a powerful tool for visualizing the electron beam-sensitive materials at atomic resolution, thus, providing new opportunities for imaging the exact configurations of metal species in the various channels of zeolites. This emerging topic summarizes recent progress utilizing iDPC-STEM-related technique for determination of the structures of metal species in zeolites that should offer insights into the structure-property relationships of zeolite-supported metal catalysts. A brief perspective about the new TEM technique is also presented, showing prospects in this field that will stimulate further scientific research in zeolite-supported metal catalysts.
