Abstract
The effects of a hydrogen pretreatment on the activity and reaction intermediate in a C 3 H 6– D 2 reaction over a Ni–Cu alloy as well as Ni metal catalysts were investigated in detail by applying an isotope tracer technique. Ni metal and Ni-rich alloy catalysts, cooled down to the reaction temperature under a hydrogen atmosphere (D-surface), exhibited low activity compared to that of a surface evacuated before cooling (E-surface). For Cu-rich alloy ...
