The project aims at the high resolution analytical microscopy of mesoporous matrices as well as of the linkage and position of the active catalysts. To this end, correlative microcopy is suggested that combines the methods of electron microscopy with the single-atom analysis of atom probe tomography. Major methodical developments are required for the atom probe tomography. Filling of the pores with contrasting liquids, a subsequent cryo-preparation, cutting to nanometric needles by focused ion beams and the direct transfer of these samples between the dual beam microscope and the atom probe are the essential steps of the planned innovation.
