Pd/H-Beta catalysts: Characterization and reactivity in piperonyl alcohol selective oxidation

---

Abstract.
Pd/H-Beta catalysts with different silica-to-alumina ratio prepared by an impregnation method have
been studied by XANES/EXAFS, IR, XRD and TEM. It was shown that palladium in calcined Pd/H-Beta
samples exists as palladium oxide that can be easily reduced to Pd metal. The catalysts were tested in
selective oxidation of piperonyl alcohol to piperonylaldehyde at 80 oC. The Pd/H-Beta zeolite catalysts
with the lowest silica-to-alumina ratio possess the highest catalytic activity in benzylic alcohol oxidation
reaction.

Keywords: Pd/H-Beta zeolites, XAS, IR, TEM, Piperonyl alcohol oxidation
