摘要：

Structural information obtained by EXAFS spectroscopy concerning the metallic phases present in oxide-supported metal catalysts, and in some cases their precursors, is reviewed. Special attention is given to catalysts containing one Group VIII metal or copper; bimetallic catalysts are considered briefly. The technique is particularly valuable where it can detect the chemical evolution of the active phase or where it can reveal morphological changes in the structure or nuclearity of metal clusters or small metal crystallites in different reaction environments.
