Figure 6.
(A) Catalytic activities of Pd–CeO2 CASs, Pd/CeO2-imp, and pure CeO2 CASs for CO oxidation and (B) the cycling testing of Pd–CeO2 CASs at alternating temperatures of 600 and 85 °C (the feed gas of 1 vol % CO in air and GHSV of 40 000 mL/(gcat·h)). (C) Kinetic data of CO oxidation on Pd–CeO2 CASs and Pd/CeO2-imp (CO conversion was kept <10%). (D) CO oxidation activities of unsupported Pd–CeO2 CASs and subsequently supported Pd–CeO2 CAS/Al2O3 catalysts (GHSV of 60 000 mL/(gcat·h)).
