Dissertation ETH No. 19121 * Synthesis, Characterization, and Catalytic Function of Zeolites and Zeotypes * A dissertation submitted to the Swiss Federal Institute of Technology (ETH) Zurich For the degree of Doctor of Sciences Presented by Nadiya Danilina Dipl.-Chem., Technical University of Dresden, Germany Born on June 4, 1983 Citizen of Ukraine Accepted on the recommendation of Prof. Dr. Jeroen A. van Bokhoven, examiner Prof. Dr. Ive Hermans, co-examiner Zurich 2010 Summary Summary Zeolites and zeotypes are widely used as catalysts in acid-catalyzed reactions. The main field of their application is in the petrochemical industry, where they are used on a large scale to catalyze cracking, alkylation, and isomerization reactions. Development of the optimal catalyst for a specific reaction is one of the main goals of research on zeolites. To design a catalyst for a certain application, the physicochemical properties of the zeolite, the mechanism of a reaction, and the structure-selectivity performance are essential. The main questions are therefore, what is the active site in a zeolite, where is it, how to reach it, and how does it function in a specific reaction? This t
