通过结合透射电子显微镜、电子衍射和高角度环形暗场扫描透射电子显微镜，对由铂微晶组成的具有几纳米周期性的三维网络进行了检查。已经澄清的是，网络的平均三维结构与二氧化硅介孔材料模具的平均三维结构略有偏差。已经发现存在局部变形、铂晶体成分的错误取向以及网络的缺陷结构。三维电子显微镜观察复杂构型纳米材料的有效性和重要性已被证明。
Three-dimensional networks with periodicity of several nanometres consisting of platinum crystallites have been examined by a combination of transmission electron microscopy, electron diffraction and high-angle annular dark-field scanning transmission electron microscopy. It has been clarified that the average three-dimensional structure of the networks deviates slightly from that of the mould, a silica mesoporous material. The existence of local distortion, misorientation of constituent platinum crystals and a defect structure of the networks have been found. The effectiveness and the importance of three-dimensional electron microscopy observations of nanomaterials with complicated configurations have been proved.
