Abstract:
PtFe/Ce0.75Zr0.25O2 catalysts were prepared using deposition and impregnation techniques and tested in water gas shift reaction in reformate-simulated feed gas. For the catalyst prepared by subsequent deposition of the metals it was observed that iron (mole ratio Pt:Fe ≈ 1.5) provides for inhibition of side reaction of methanation at the temperatures up to 350 °C. The water gas shift reaction rate per Pt surface area was also increased compared to the catalyst without iron (Pt content was the same). XPS analysis of PtFe/Ce0.75Zr0.25O2 showed that there are Pt0 and Fe2+ cations on the surface in H2 atmosphere at 150–350 °C. In situ DRIFTS results demonstrated stronger CO adsorption on the Pt-support interfacial sites and higher CO2 formation rate in the gas phase going from Pt to Pt-Fe system.
