dc.description.abstract	The combustion synthesized Ag/CeO(2) catalysts have been characterized by Extended Xray Absorption Fine Structure (EXAFS) spectroscopy at the Ag K-edge.It has been found that Ag+ like species is present in 1 percent Ag/CeO(2) catalyst, whereas mostly Ag metal clusters are found in 3 percent Ag/CeO(2).The analysis of EXAFS spectra indicates that about one oxygen atom is coordinated to Ag central atom at a distance of 2.19 Angstrom in 1 percent Ag/CeO(2) catalyst along with eight coordinated Ag-Ag bond at 2.86 Angstrom.The Ag-O bond is absent in 3 percent Ag/CeO(2).	en_US
