For the combustion of methane, a partial replacement of platinum by rhodium leads to a significantly improved light-off behavior of the corresponding mixed Pt-Rh/γ-Al2O3 catalysts compared to a catalyst containing only Pt supported on γ-Al2O3. For

The effect of metal oxide (CeO2, Al2O3 and ZrO2) support and In2O3 co-supported Pt catalysts has been investigated on steam reforming of methanol in microreactors. CeO2, Al2O3 and ZrO2 were prepared by the sol-gel method and they were used as a suppo

The influence of morphology and crystalline facets of nanoshaped ceria oxide support in Rh/CeO 2 and Rh/CeO 2/Al 2O 3 catalysts have been investigated by oxidative steam reforming of propylene glycol in microreactors at 630 °C at S/C = 3.5 and O/C =

In this work Pt based mono and bimetallic catalysts were deposited into microchannel testing reactors and tested under conditions of water-gas shift (WGS). All the catalysts contained 25% of CeO 2 and a metal loading of 2.5% or 5.0% (nominal wt.%). T
