| Abstract: | The role of the so-called oxygen storage and release capacity (OSC) in promoting the activity of noble metals in the three-way catalysts (TWCs) is critically discussed. It is shown that the promoting effects of CeO2 in the TWCs cannot be attributed to a simple redox type of effect according to the reaction CeO2 ? CeO2 ? x + x/2O2, since multiple and sometimes intriguing effects of CeO2 promoter have been observed, particularly in the latest generation of TWCs containing modified CeO2–ZrO2 mixed oxides. |
