Abstract Visualizing and measuring the gas distribution in close proximity to a working catalyst is crucial for understanding how catalytic activity depends on structure of catalyst. However, existing methods are not able fully determine during process. Here we report reaction can be imaged situ with high spatial (400 μm) temporal (15 μs) resolution using infrared planar laser-induced fluorescence. The technique demonstrated by monitoring, real-time, carbon dioxide oxidation monoxide above...
Structural and morphological characterizations of bimetallic Pd–Pt/Al2O3 model catalysts are performed using X-ray diffraction, absorption spectroscopy, transmission electron microscopy, CO chemisorption. Further, the were studied under oxidizing reducing conditions both spectroscopy low-energy ion scattering spectroscopy. For as-prepared catalysts, existence alloyed Pd–Pt particles (tetragonal) PdO was found for samples calcined at 800 °C. is present in form crystals surface or as isolated...
Graphical Abstract
Commercial three way catalysts have limited capacity towards reducing NOx in the presence of excessive oxygen. This prevents lean-burn combustion concepts from meeting legislative emission standards. A solution decreasing emissions excess air is use a passive-SCR system. Under rich conditions ammonia formed over an formation catalyst, stored SCR and its turn reacts with under lean engine conditions. Here up-scaled Pt/Al2O3 Pd/Al2O3 as well commercially Pd-Rh based three-way catalyst (TWC)...
