三维透射电子显微镜（3D-TEM）通过对样品进行多次成像并结合图像分析来实现，为材料科学提供了一种获取复杂固体材料三维信息的新方法。在这里，我们报告的第一类的结果，已获得沸石材料。金属/沸石晶体（Ag/NaY）的3D重建的虚拟横截面和体绘制给出了关于银颗粒（直径10-40 nm）的位置的明确信息。酸浸丝光沸石的3D重建的虚拟横截面显示了三维中孔通道系统（直径3-20 nm），其清晰度和清晰度前所未有。
Three-dimensional transmission electron microscopy (3D-TEM), effectuated by multiple imaging of a sample combined with image analysis, offers a new approach in materials science to obtain 3D information of complex solid materials. Here we report first-of-its-kind results that have been obtained with zeolite materials. Virtual cross-sections and volume rendering of the 3D reconstruction of a metal/zeolite crystal (Ag/NaY) give unequivocal information on the location of the silver particles (10-40 nm in diameter). Virtual cross-sections of the 3D reconstruction of an acid-leached mordenite show the three-dimensional mesoporous channel system (3-20 nm in diameter) with a clarity and definition not seen before.
