摘要：

The effect of water on carbon monoxide oxidation over alumina-supported CuO and CuCr2O4 catalysts has been examined. The results suggest a relation between catalyst deactivation effected by the introduction of water to the reaction mixture and sintering of copper. The copper-chromite phase apparently protects the catalyst against this detrimental effect. © 1990.
