Surface structures of SiO,-supported niobium catalysts prepared by use of a Nb-monomer complex, a Nb-dimer complex, Nb pentaethoxides and Nb pentachlorides as precursors have been determined by means of EXAFS and XANES. These different Nb structures on SiO, have been characterized by ethanol dehydro
