Abstract
The structure of Pd/Cu catalysts on gamma-alumina for nitrate/nitrite ion r emoval from drinking water is investigated. EXAFS spectra at the K edge of both elements show that small clusters with the basic crystal structure of bulk palladium metal are formed. The size of the clusters is estimated from the range of photoelectron scattering paths, and from the average number o f first neighbors. Both estimates indicate clusters of about 12 atoms, ie t wo neighbor shells.
