Abstract

XPS and IR spectroscopy indicate that the electron density of the supported metal clusters in Pd/LTL catalysts is a function of the support acidity/alkalinity. In addition, the neopentane and propane hydrogenolysis TOF's increase with increasing support acidity from alkaline to acidic. The changes in spectroscopic and catalytic properties are due to electron deficient Pd on acidic supports, as previously proposed, and electron rich Pd on alkaline supports.
