Resumen:
Pt-based catalysts
have been widely investigated in WGS reaction (CO + H2O ↔ CO2
+ H2) because the CO conversion turnover rate is higher on Pt in comparison to other
noble metals. In particular, Pt/CeO2has been reported as a promising WGS catalyst due to its high activity but deactivates on stream. Several researchers have studied the WGS
reaction on Pt/ZrO2 catalysts due to ZrO2 high hardness,
good mechanical resistance and thermal stability. The WGS reaction has been
also studied on Pt supported on binary Ce-Zr mixed oxides, but conclusions
regarding catalysts activity and stability are not conclusive. In this work, we
study the WGS reaction on Pt/CeO2, Pt/ZrO2 and Pt/CexZr1-xO2
