  • Pt/CeO2-C catalysts with CeO2 pre-calcined at 300~600 °C were synthesized by combining hydrothermal calcination and wet impregnation method. The effects of the pre-calcined CeO2 on the performance of Pt/CeO2-C catalysts for methanol oxidation have been investigated. The Pt/CeO2-C catalysts with pre-calcined CeO2 at 300~600 °C have shown an average particle size of 2.6-2.9 nm, and exhibited better methanol electro-oxidation catalysis activity than the commercial Pt/C catalyst. Specifically, the Pt/CeO2-C catalyst with pre-calcined CeO2 at 400 °C displayed the highest electrochemical surface area (ECSA) value at 68.14 m2 g−1Pt and If/Ib ratio at 1.26, which are far larger than that of the commercial Pt/C catalyst at 53.23 m2 g−1Pt and 0.79 respectively, implying the greatly enhanced CO tolerance performance.

Abstract: Pt/CeO2-C catalysts with CeO2 pre-calcined at 300~600 °C were synthesized by combining hydrothermal calcination and wet impregnation method. The effects of the pre-calcined CeO2 on the performance of Pt/CeO2-C catalysts for methanol oxidation have been investigated. The Pt/CeO2-C catalysts with pre-calcined CeO2 at 300~600 °C have shown an average particle size of 2.6-2.9 nm, and exhibited better methanol electro-oxidation catalysis activity than the commercial Pt/C catalyst. Specifically, the Pt/CeO2-C catalyst with pre-calcined CeO2 at 400 °C displayed the highest electrochemical surface area (ECSA) value at 68.14 m2 g−1Pt and If/Ib ratio at 1.26, which are far larger than that of the commercial Pt/C catalyst at 53.23 m2 g−1Pt and 0.79 respectively, implying the greatly enhanced CO tolerance performance.
