found that Pt/SbOxcatalysts wereactive for the selectiveoxidation of i-C4H10and i-C4H8to methacrolein (MAL) at 773 K. TheSbOxitself was inactive for the selectiveoxidation of i-C4H10, whilei-C4H8was converted to MAL on theSbOx. Small amounts of Pt (0.2–0.72 wt%)supported on the SbOxpromoted thei-C4H10oxidation with good selectivity to MAL(typically 50–60%) and MAL+i-C4H8(80–90%). The selective oxidation
据发现,铂/非晶态SbO X催化剂wereactive为IC的选择性氧化4 ħ 10和IC 4 ħ 8在773 K. TheSbO至甲基丙烯醛(MAL)X本身是无活性的对IC的selectiveoxidation 4 ħ 10,whilei-C在SbO x上将4 H 8转化为MAL 。负载在SbO x上的少量Pt(0.2–0.72 wt%)促进了thei-C 4 H 10氧化,并对MAL(通常为50–60%)和MAL + iC 4 H 8(80–90%)具有良好的选择性。i-C的选择性氧化4 ħ 8到MAL还通过显着的Pt /非晶态SbO的Pt.The性能增强的X为THEI-C催化剂4 ħ 10选择性氧化可以是Pt粒子的attributedto结合的催化改性withSbO ý(Ý < X andSb)6 Ô 13产生在氧化条件下。

Examples of reactions which are termolecular near room temperature and gradually switch over to complex-forming bimolecular reactions with increasing temperature are discussed. The Sb/O
