摘    要:白钨石ABO_4复合氧化物在烯烃氧化中起着重要作用,但在烷烃催化氧化中的研究并不多,有关稀土氧化物催化剂的研究则更少。本文以Mg、La、Ce、Eu的钼酸盐作为甲烷选择氧化催化剂,每种催化剂制成不同A/B值系列,以考察催化剂结构和氧化活性的关系。

关 键 词:甲烷  氧化  甲醛  CeMoO4

Abstract:The ABO4 type of Mg, Ln(La, Ce, Eu)molybdates has been used as catalysts to convert CH4 to HCHO. ESR, TPR and XRD measurements show that molybdenum near the neighbour oxygen ions take part in oxidation reaction. When molybdenum ions were fixed as the atom B and the atomic ratio A/B was changed, the atoms at site A were substituted by Mg,La,Ce,Eu, the structure of catalysts take varied type, such as , a-MgMoO4, a-La2(MoO4)3, Eu2(MoO4)3 etc. The selectivity of formaldehyde increased according to the following .order MgMoO4
Keywords:Methane  Formaldehyde  Cerium molybdate
