Effect of Ce³⁺/Ce⁴⁺ Couple on Selective Hydrogenation of Crotonaldehyde over Pt/CeO₂ Catalyst

Abstract:

By pretreatment of Pt/CeO₂ catalysts with high temperature reduction and subsequent low temperature reoxidation, the concentration of Ce³⁺ species in the Pt/CeO₂ catalysts could be adjusted, while at the same time the Pt particle size remained constant. Thus the pure effect of Ce³⁺/Ce⁴⁺ couples on the selective hydrogenation of crotonaldehdye could be explored. The investigation provided direct proofs supporting that Ce³⁺ species favors the crotyl alcohol selectivity.
