The oxygen exchange mechanism between C 18 O 2 and CeO 2 and the role of Pt in this process have been studied in an advanced TAP reactor in the 200–600°C temperature range. For bare and Pt-containing CeO 2 , the exchange of the oxygen atoms of C 18 O 2 takes place in the whole temperatures range studied, and the oxygen exchange rate increases with temperature...
