Exafs studies on SiO2-attached Nb-oxide catalysts and catalysis

Abstract

Metal oxides molecularly deposited on high surface area supports may be one of the most promising catalysts from the viewpoint of effective use of resources and may also be of great interest from the viewpoint of new surface/interface chemistry. On the support surfaces unique structures of active sites are possible to create. The metal sites prepared by the attachment of suitable organometallic precursors are also affected electronically through a direct interaction at interface. Such molecularly designed active structures can be well characterized by means of EXAFS. The tailored metal catalysts may have great advantages for a deeper understanding of essential factors or origin of solid catalysis and catalyst design on a molecular level.
