- Analysis of catalysts surface - IR, XAFS, and XEOL Studies
Inorganic chemistry embraces all of the elements so far found and includes wider varieties ranging from atomic or molecular basis to the solid materials. My interesting is related to the solid materials, especially, to the catalytic properties of solid inorganic compounds: surface properties of solid materials. In recent ten years, we mainly focus our attention on the specific adsorption feature of copper-ion-exchanged zeolite (CuMFI) system: prominent adsorption feature of CuMFI for dinitrogen molecules at 300 K. We intend to clarify the states of active sites for small inorganic molecules, i.e., N2 and H2, in CuMFI by utilizing several spectroscopic techniques. We are mainly utilizing XAFS, XEOL, IR, Raman, and PE methods for analyzing surface structures and electronic properties of solid inorganic materials. Through such investigation, we are aiming at preparing hitherto unknown kinds of materials by utilizing specific properties of solid surfaces and ultimately designing new and effective catalysts in various reactions.
