Crystallites in catalysts

Specific featiu>es of palladlvun catalysts vdiich pass alkaline treatment (procedure employed often in the catalyst preparation [10]) may be derived from the data in Table 1. Due to adsorption on carbon support, the hydroxy-species are stabilized against agglomeration (which occurs in solutions) and, so, still small particles of metallic palladium can be produced. TEH examination showed that Pd crystallites in catalysts 1 and 2 are indistinguishable in size (1-2 nm 3-8 nm as predominant size in sample 3 -1). Moreover, fraction of the palladlvun exposed proved to be substantially higher in catalysts 2 than in catalysts 1. And...
