This communication describes the synthesis of Pt@CeO2 core-shell catalysts for the application of highly efficient CO oxidation, where the 50% CO conversion temperature is lower than 200 degrees C. Pt@CeO2 is thermally stable as no deactivation occurs during the 70 h reaction, and the morphology is unchanged even after 700 degrees C thermal treatment.
