ABSTRACT:
An ultra-fine gold particle-immobilized oxide is produced by a method which comprises adding an alkali compound to an aqueous solution containing a gold compound and a water-soluble metal salt thereby giving rise to a coprecipitate in the aqueous solution, separating the coprecipitate from the aqueous solution, and calcining the separated coprecipitate. This method is characterized by allowing the presence of a carboxylic acid or a carboxylate in the aqueous solution from the beginning or after the occurrence of the coprecipitate.
