Fe和Mn氧化物价态的电子探针分析已见文献报导。本文研究Cu,Ni,Co,Fe,Mn,Cr及其氧化物的I_(Lα)/I_(Kα,I_(Lα)/I_(Lβ)强度比和Mo,Nb,Zr及其氧化物的I_((Lβ)_2)/I_((Lα)_1),I_((Lγ)_1)/I_((Lα)_1)强度比的价态效应,观察到强度比按一定规律随价态而变化,并利用此效应分析催化剂的价态。通过分析可以了解催化剂反应前后以及不同制备条件下价态的变化,这对了解催化过程有着重要的意义。 Electron probe analysis of valences of Fe and Mn oxides has been reported in the literature. In this paper, I_ (Lα) / I_ (Kα, I_ (Lα) / I_ (Lβ)) intensity ratio of Cu, Ni, Co, Fe, Mn, Cr and their oxides and I_ (Lβ) _2) / I _ ((Lα) _1), I _ ((Lγ) _1) / I _ ((Lα) _1) and the intensity ratio changes with the valence state according to a certain rule. And analyze the valence state of the catalyst by using this effect.Analysis of valence state before and after the catalyst reaction and under different preparation conditions can be of great significance for understanding the catalytic process.
