Abstract:

The effect of water in the reactant gas on the catalytic activity for CO oxidation over Au/Co₃O₄ catalysts has been investigated. Water in the reactant gas had a negative effect on the catalytic activity for CO oxidation in Au/Co₃O₄ catalyst. Furthermore, it was observed that the average particle size of gold on Au/Co₃O₄ catalysts increased after stability testing both in dry and wet conditions.
