Metal Clusters in Zeolites

Abstract

The sections in this article are Introduction Nano Clusters of Metal versus Macroscopic Metals Preparation of Mono‐ or Bimetal Clusters in Zeolite Cavities Ion Exchange Calcination Reduction Interaction of Metal Clusters and Zeolite Protons B rønsted Acids in Zeolites Metal Clusters as Lewis Bases Chemical Anchoring Heterogeneous Catalysis by Single Metal Atom Sites Electron Deficiency Is Bifunctionality due to “Shuttling” between Sites or to “Collapsed Sites”? Metal Oxidation by Protons, Selective “Leaching” Effects of Zeolite Geometry on Catalysis Transport and Transition State Restrictions Collimation of Molecules in Pores Types of Pore Diffusion in Zeolites; Effects on Apparent Activation Energy Beneficial Damage of Zeolite Matrix by Growing Metal Particles Conclusions Acknowledgments
