Abstract

We show that an appropriate analysis of the electron energy loss spectra in relation to the Cr-O bonds gives a reliable methodology to obtain the oxidation state in chromium oxides. It is based on the energy difference between the Cr L(3) and O K edges, which acts as a measure of the binding energy difference between the Cr 2p(3/2) and O 1s core levels.

摘要

我们表明，适当分析电子能量损失谱与 Cr-O 键之间的关系，可以为获得氧化铬中的氧化态提供可靠的方法。它基于 Cr L(3) 和 O K 边缘之间的能量差，该能量差可用作 Cr 2p(3/2) 和 O 1s 芯能级之间的结合能差的量度。
