【Abstract】

<正> Conventionally, supported metal catalysts are prepared by impregnating supports in aqueous solutions containing active metals. The properties of catalysts prepared by this method are not fully reproducible because of high surface tension of water. The most evident fact is to lead to inhomogeneity in distribution of the metal supported. Moreover, this inhomogeneity will be usually enhanced during the calcination process at high temperature.
