Abstract
Auger electron spectroscopy of an amorphous Cu 61Zr 39 alloy sample indicates copper and zirconium enrichment on the inner and outer sides, respectively. Dehydrogenation of 2-propanol in hydrogen on this alloy results in bulk crystallization, changes in its surface morphology and a significant copper enrichment on both sides. The increases in the activity and copper surface area of the alloy during the catalytic reaction are explained by copper segregation.
