摘要

铁钼氧化物不仅是甲醇氧化制甲醛的催化剂

也是甲醇氨氧化制氢氰酸的优良催化剂之一.有关前者的活性组分和催化性能的报道较多

后者报道不多

用于沸腾床上铁钼催化剂未见报道.本文用多种实验方法研究了用于沸腾床的铁钼催化剂活性组分及其催化作用.

Abstract

The catalytic activity of iron-molybdenum catalyst in ammoxidation of methanol to HCN in boiling bed microreactor has been investigated with XRD

Mossbauer Spectrum

ESR and XPS. The studies of XRD and IR indicated that iron and molybdenum ions were present as Fe2(MoO4)3

MoOs and α-Fe2O3 in the catalyst

and that the change of the relative content of Fe2(MoO4)3 and catalyticac activity showed corresponding correlation in a peak shape with Fe/Mo ratio. Mossbauer Spectrum

ESR and XPS analysis showed that iron and molybdenum would be present as Fe3+ and Mo6+ in Fe2(MoO4)3

Fe2O3·xMoO3 and α-Fe2O3·Fe2 (MoO4)3 was in coordination of an octahedron

while Fe2O3·xMoO3(x<3) showed im perfect coordination.The former could be a basic active component

the latter was very likely the surface active center. All the three components synergistically performed the function of selective oxidation.
