Evaluation of Manganese Oxide Octahedral Molecular Sieves for CO and C3H6 Oxidation at Diesel Exhaust Conditions

“…Interesting, in the presence of C 3 H 6 , MnO(3 × 3) exhibited much better CO oxidation activity than MnO(2 × 2) and MnO(1 × 1), which was quite different from the results of CO oxidation without C 3 H 6 in the reactant. The catalytic performance of some typical catalysts for the oxidation of CO and propylene were listed in Table 2 (Seo et al, 2021;Li et al, 2019;Ma et al, 2018;Li et al, 2021;Hazlett et al, 2017;Wang et al, 2019;Rida et al, 2006;Tan et al, 2020;Liu et al, 2020;Březina et al, 2020). It was seen that noble metal catalysts had outstanding low-temperature activity below 250°C, while the catalytic activity of transition metal catalysts was generally lower than that of noble metal catalysts.…”

Site requirements for inhibition-free CO oxidation over silica-supported bimetallic PdCu alloys

“…6 DOCs are typically Pt and Pd and their alloys supported on various oxide supports. [7][8][9][10][11][12][13] Pt is highly active for the above reactions, while the addition of Pd increases the catalysts' resistance to sintering in addition to facilitating oxidation. 11,14 Standard diesel vehicles normally operate at 327 °C.…”
