A dynamic structural behavior of Pt nanoparticles on the ceria surface under reducing/oxidizing conditions was found at moderate temperatures (<500 °C) and exploited to enhance the catalytic activity of Pt/CeO2‐based exhaust gas catalysts. Redispersion of platinum in an oxidizing atmosphere already occurred at 400 °C. A protocol with reducing pulses at 250–400 °C was applied in a subsequent step...
A novel nanoparticulate catalyst of copper (Cu) and ruthenium (Ru) was designed for low‐temperature ammonia oxidation at near‐stoichiometric mixtures using a bottom‐up approach. A synergistic effect of the two metals was found. An optimum CuRu catalyst presents a reaction rate threefold higher than that for Ru and forty‐fold higher than that for Cu. X‐ray absorption spectroscopy suggests that in the...
