Sulfides, Zeolites, and Nanotowers

Abstract

Three new classes of materials, which we developed and use in our catalytic research, are described. Layered and intercalated sulfides are studied for their use as model compounds for hydrodesulfurization catalysis. Dealuminated zeolites and other mesoporous materials contain mesopores which enhance diffusion and, thus, the effectiveness of zeolitic materials in liquid-phase reactions. Using lithographic techniques, nanotowers are manufactured from layers of metals and insulators placed on silicon wafers. The nanotowers are studied as model catalysts, especially for investigating size effects in heterogeneous catalysis.
