Binary Supported Nickel Catalysts for the Deuterium Exchange Reaction between Hydrogen and Water Vapour

Nickel catalysts supported by Fe 2 O 3 , CuO, MnO and CcO were prepared from the corresponding metal nitrates. Chemical treatment of the catalysis teas carried out at room temperature, while thermal treatment was made at 350 °C. The total surface area of the catalysts were measured by nitrogen adsorption at - 195 °C using the BET-equation. The specific metallic surface area was measured by hydrogen chemisorption at liquid temperature. The activity of the catalysis as tested for the isotopic exchange reaction of deuterium between hydrogen and water vapour. The results obtained showed that Ni - Fe 2 O 3 , Ni - CuO and Ni - MnO catalysts exhibit catalytic activity for the deuterium exchange between hydrogen and water vapour, while the catalyst supported with CeO has no activity for such an isolopic exchange reaction.
