Abstract

Abstract : 0.6Pt/meso-Co3 O4 exhibits the highest catalytic activity of acetylene oxidation at 120 °C and good stability for at least 60 h. Abstract : Three-dimensionally ordered mesoporous Co3 O4 (meso-Co3 O4 ) and its supported Pt catalysts were synthesized for the catalytic oxidation of acetylene. All the catalysts formed mesoporous structures and possessed high surface areas of 110–122 m 2 g −1 . Meso-Co3 O4 -supported Pt catalysts exhibited highly catalytic performances, and the 0.6Pt/meso-Co3 O4 catalyst gave the lowest temperature of 120 °C for acetylene oxidation. It was concluded that the ordered mesoporous structure, with plenty of structural defects, good low-temperature reducibility and the high concentration of active oxygen species were responsible for the excellent catalytic performance of 0.6Pt/meso-Co3 O4 .
