Effect of hydrogen treatments on ZrO2 and Pt/ZrO2 catalysts

Abstract

ZrO2 and Pt/ZrO2 catalysts have been investigated by TPR, hydrogen chemisorption, TPDH and in the conversion ofn-hexane. At high temperature, ZrO2 takes up hydrogen. High temperature hydrogen treatment is a precondition of the catalytic activity in then-hexane conversion. Possibly, catalytically active acid sites are formed by this hydrogen treatment. The high temperature hydrogen treatment induces a strong Pt-ZrO2 interaction.
