Conclusions
-
1.
Isotope exchange between H2 and D2 occurs on metallic-copper powder and on reduced copper-containing catalysts at 100–200°C, which indicates dissociative hydrogen adsorption on them.
-
2.
The absence of exchange on oxidized samples of the same catalysts indicates that dissociative hydrogen adsorption occurs on the reduced metal surface.
