To understand the higher catalytic properties, the structure of 2 at. % palladium supported on TiO2 has been investigated by Extended X-ray absorption fine structure (EXAFS) spectroscopy. This nanocatalytic material of composition Ti0.98Pd O-0.02(2-delta) has been synthesized by solution combustion method The analysis of EXAFS shows the oxide ion sublattice aroundPd ions is destabilized in the solid solution. Instead of ideal six coordination, Pd ion has 4+2, coordinations creating long and short bonds. The long Pd-O bonds are at 2.52 angstrom which are much higher than average TiO bonds of 1.947 angstrom.
