[show abstract][hide abstract] ABSTRACT: The truth about Cats: The metal-oxide interface of a Pd-Rh/CeO catalyst was studied in the context of developing active, selective and durable solid catalytic materials for the production of hydrogen from renewables. The presence of a stable contact between finely dispersed transition-metal clusters (Pd and Rh) on the nanoparticles of the CeO support leads to a highly active and stable catalyst for the steam reforming of ethanol.
[show abstract][hide abstract] ABSTRACT: The work presents a study by temperature programmed desorption, in situ infra red spectroscopy and catalytic steam reforming
of ethanol (SRE) over CeO2 and the bimetallic Pd-Rh/CeO2; comparison with the monometallic catalysts (Rh/CeO2 and Pd/CeO2) was also made for the steam reforming study. Comparing TPD of ethanol over CeO2 and the bimetallic catalysts indicated two main differences: the direct oxidation route to acetate over CeO2 is suppressed by the presence of the metal and the lowering of the dehydrogenation reaction temperature by about 100 K. In situ
IR study indicated that the bimetallic catalyst breaks the carbon–carbon bond of ethanol at low temperature
