Electron Tomography of Mesoporous Silica for Gas Sensor Applications
The complex 3-D structures of some materials must be visualized and analyzed for structural characterization, often as part of quality control of a synthetic process. In this work we applied electron tomography for the 3-D reconstruction of a mesoporous SBA-15 silica structure doped with platinum as a catalytic additive. We used a 200kV JEOL 2011 transmission electron microscope with a ±60 degrees tilting holder. Digital Micrograph software was used for automatic acquisitions and Imod software for the digital reconstruction. Moreover, we use a combination of microscopy techniques: scanning electron microscopy and confocal scanner laser microscopy in reflection mode.
