Abstract
Lattice imperfections have long been considered to be possible sites of catalytic activity in solids. Considerable research work has been undertaken with the aim of demonstrating such a relationship; but discrepant results have been reported in this field (1 – 4) Nevertheless, in some recent publications (5 – 7) a good correlation has been found between activity of deformed metal sheets and their lattice-defect content, mainly dislocations, as shown by structural investigations. Studies on metal powders are not so numerous. This is mostly due to the difficulty in assessing quantitatively the defect structure of powder catalysts. Also in this sphere, different explanations have been suggested to account for changes in powder activity originated by thermal and mechanical treatment (8 – 9).
