Supported Nickel-Cobalt Oxide Catalysts for the Isotopic Exchange of Deuterium between Hydrogen and Water Vapour

Abstract

The specific catalytic activity of supported nickel-cobalt (II) oxide catalysts for the isotopic exchange of deuterium between hydrogen and water in the vapour phase was tested. The specific surface area of the catalysts was evaluated by nitrogen adsorption at −195.8 °C and application of the BET-equation. The specific metallic surface area for these catalysts was carried out at liquid nitrogen temperature by hydrogen adsorption. Comparison between the specific activity of the catalysts and the specific surface area and specific metallic surface area teas made. The results of this study indicated that nickel catalysis supported with 15 – 20 mole% CoO exhibit a relatively high catalytic activity for the isotopic exchange reaction between hydrogen and water vapour, high specific surface area and high specific metallic surface area.
