| Abstract(E) | To enhance the performance of three-way catalyst (TWC) and develop a numerical model, elucidating the oxygen release and storage mechanisms is key. In this study, oxygen isotope labeling experiments were conducted using a model catalyst consisting of dense oxygen storage material substrate coated with a precious metal. The effects of the TWC composition, such as the precious metal and the ceria-zirconia composition, on the oxygen storage distribution inside were visualized and analyzed. |
