Palladium supported catalysts

Palladium supported catalysts

New supported Pd catalysts with a Pd content of 0.001-2 wt.%, in which the Pd is present in a surface layer less than 5000 nm thick, are obtd. by treating a support comprising Al2O3, SiO2, ZrO2 and/or TiO2 with a Pd sol. either by impregnating the support with the sol or by spraying the sol onto the...

Zusammenfassung:New supported Pd catalysts with a Pd content of 0.001-2 wt.%, in which the Pd is present in a surface layer less than 5000 nm thick, are obtd. by treating a support comprising Al2O3, SiO2, ZrO2 and/or TiO2 with a Pd sol. either by impregnating the support with the sol or by spraying the sol onto the heated support.
