Identifying and illustrating the fine structures of active sites play an important role for tuning selectivity,c onversion and stabilityo ft he catalysts. [1,2] With the development of nanoscience and nanotechnology,m any novel approaches have been developed to tailor and control morphology,a rchitecture, and surface/interface structure of the complex solid catalysts at atomic level. All of the investigations need high-resolution characterization methods to detect the active site/phase of ac atalyst.Electron microscopy (EM) enables us to obtain significant details at atomica nd sub-electron-volt scales, ranging from the morphology,e lemental distribution,b ulk/surface/interface structure, chemical and crystallographic information, and valence state, to dynamic process (e.g.,t he sintering of nanoparticles in heating and the structure evolution simulated by electron beam), as shown in Figure 1. Traditionally,t oe xplore the structure-function relationship of ag iven catalyst, and to aid in the understanding of the mechanism, catalysts tructures were compared before and after ar eaction by analyzing the evolution of the active sites. Analysis could be achieved with av ariety of modes on routine TEMs (e.g.,high-resolution transmissionE M( HRTEM), scanning TEM (STEM) and electron diffraction( ED) or affiliated spectroscopyt echniques( e.g.,e nergy dispersion X-ray spectroscopy( EDX) and electron energy loss spectroscopy (EELS)).Itshould be mentioned that TEM and STEM images are twodimensional (2D) projections derived from 3D objects. The interpretation of S/TEM images combining with image simulation and quantitative analysis are essential and give invaluable information about the structuralf eatures of complex nanocata- Figure 1.

“…Als Beispiel zeigt Abbildung 11 das Bild eines Partikels eines Silberkatalysators, der in der von R. Schlçgl geleiteten Abteilung untersucht wurde. [12] [15] Neben den Pt-Atomen des Substrats erkennt man Paare adsorbierter O-Atome, die aus der dissoziativen Adsorption resultierten. Bei dieser tiefen Temperatur sind die adsorbierten Atome nahezu unbeweglich.…”

“…Die künftigen Nobelpreisträger sind mit einem roten Stern gekennzeichnet.Abbildung 11. a) Transmissionselektronenmikroskop(TEM)-Aufnahme eines Ag-Katalysatorteilchens mit atomarer Auflçsung [12]. Bei dieser Technik werden üblicherweise Edelgasatome durch das hohe elektrische Feld vor einer scharfen Metallspitze ionisiert, und die Ionen werden dann auf einen Leuchtschirm hin beschleunigt, wo ihre Auftreffpunkte die Stellen markieren, an denen die Ionisation erfolgt war.…”

VorwortAm 28. Oktober 2011 feierte das vormalige Kaiser-Wilhelm-Institut für Physikalische Chemie und Elektrochemie (das heutige Fritz-Haber-Institut der Max-Planck-Gesellschaft) in Berlin-Dahlem den 100. Jahrestag seiner Gründung. Seine Geschichte wurde bereits in einer Monographie [1] und in einem Artikel von B. Friedrich et al. [2] ausführlich beschrieben. Das vorliegende Essay ist eine mehr persçnliche Schilderung, die als Vortrag zur Jahrhundertfeier gehalten wurde, und konzentriert sich im Wesentlichen auf eine Reihe von Arbeiten aus dem Institut, die zum Verständnis der Wechselwirkung zwischen Molekülen und Festkçrperoberflächen beigetragen haben.

“…with various analytic modes and associated detectors, such as for X-rays, backscattered electrons, and energy-lost electrons (Figure ), the electron microscope has advanced from a simple piece of imaging equipment to a comprehensive research toolbox indispensable for many science and technology disciplines. Apart from nanoscience and nanotechnoglogy, catalysis is one of the most important areas, where EM, particularly TEM and STEM, has found applications. − It can be said that the evolution of catalysis science is based on the ability to cope with the structural complexity of solid catalysts, which is largely made possible by the advancement of electron microscopy. , Figure shows the huge increase of the number of research papers on solid catalysts investigated by TEM annually from 1991 to 2014 in the ISI Web of Science, evidencing the significant contributions of TEM and its associated techniques to the study and development of solid catalysts.
