摘要： The invention relates to catalysts comprising palladium on a support in which the palladium is distributed in the support as an eggshell. The palladium surface area is at least 150 m2/gPd. A method for manufacturing such catalysts involves impregnating a support with an impregnation solution comprising palladium ions and citrate ions, followed by drying the resulting product. Also described is an impregnation solution comprising palladium ions, citric and/or citrate ions, and acetic acid, which is suitable for manufacturing the catalysts described.
