Electrical Conductivity Study of Pt/Ce0.6Zr0.4O2 Catalyst in Water-gas Shift Reaction

Abstract

Abstract:

The catalytic activity for water-gas shift reaction was investigated over Pt catalysts supported on different supports, such as Ce_0.6Zr_0.4O₂, CeO₂ and ZrO₂. The samples were characterized by XRD, temperature-programmed reduction(TPR) and in situ electrical conductivity to evaluate the structure and redox properties. It is concluded that Ce_0.6Zr_0.4O₂ support was a single phase solid solution with high capacity of oxygen transfer, therefore enthanced the catalytic activity of Pt/Ce_0.6Zr_0.4O₂ catalyst, for water-gas shift reaction.

Key words: Pt/Ce_0.6Zr_0.4O₂ catalyst, Water-gas shift reaction, Temperature-programmed reduction, Electrical conductivity
