Abstract: Recently, great efforts are devoted to develop new methods of preparation of high-disperse Pd-containing nanosystems (composed of metal and/or oxide substance) stabilized on oxide matrix. New approach of synthesis is usage of PdCo(μ-OOCMe)4(NCMe) complex and Ti(OBu)4 as precursors to anchor Pd on the surface of oxide matrix surface in a highly dispersed form. The present work is devoted to the structural study of this high-disperse Pd-containing nanosystem by the XAFS spectroscopy. The strong interaction between Pd and Co cations takes place in the studied system. Seemingly, Co cations incorporate into TiO2 oxide matrix, forming mixed oxides. This allows to anchor Pd cations, with the formation of the palladium oxide structures, modified by interaction with Co and Ti cations. These compounds are non-stochiometric and have typical structural features of mixed oxides. All possible structural models are discussed in detail.
