Partial Oxidation of Hydrocarbons Over Ceria Zirconia Catalysts
… Next, methane partial oxidation over ceria zirconia catalysts is studied with infrared spectroscopy. Methane and oxygen concentrations are modulated to differentiate active and spectator species via modulation excitation spectroscopy. Aromatic and alkoxy surface species modulate in …

CO and Hydrocarbon Oxidation on PD/Ceria-Zirconia/Alumina Three-Way Catalysts
… support material was compared to that of ceria-zirconia (CZO) as an alternate support with oxygen storage capacity in experimental studies. CO, propylene, and acetylene oxidation were enhanced using Pd/CZO compared to Pd/Al2O3, as observed in light-off performance tests. Differences in …

Synthesis of nanostructured materials in deep eutectic solvents
… vanadium pentoxide (transition metal oxide), ceria and zirconia (ceramic oxides). The work focuses on gaining a holistic understanding on the interaction of reline with different precursors. It is found that reline can act as an ‘all in one’ platform such as template reagent, reducing agent, …

Role of Storage Material in NOX Storage and Reduction (NSR) and Three-Way Catalysts (TWC) During Cycling Operation
… NOx conversion enhancement under fast cycling. A ceria redox pathway has only a secondary effect on NOx conversion under excess O2. Simultaneous conversion of NO, CO and C3H6 under stoichiometric conditions was carried out on catalysts containing OSM-promoted mixed precious group metal (PGM: …

Nanocomposite catalysts for soot combustion and propane steam reforming
… onto nanocrystalline supports, such as alumina, ceria, zirconia and titania. The best activity and catalyst reducibility were achieved by CuO supported on CeO2, a material known for its redox property and oxygen storage capacity. A CuO loading of 20-40 wt% presented the optimal balance between …
