结合P和O XPS谱图及元素含量分析,结果表明F-Al-O物种与P之间的化学键合作用可能是稳定亚稳态F-Al-O物种的有效途径。 Figure 3 High-resolution Al 2p (a), P 2p (b), O 1s (c) XPS spectra of fresh and spent AlPO4;...
我的文章审稿意见中有一条是这个样子的:The presented XPS spectra was obtained from the overall scanning of the materials, nevertheless, a detailed spectra of Al2p ranging from 72 ~ 76 eV should be given to support the authors' argument about the catalyst deactivation. 因为我是用 γ-Al2O3 ...
在作XPS分析时，全扫描谱能量范围一般取01200eV，因为几乎所有元素的最强峰都在这一范围之内。通过样品的全扫描谱，在一次测量中我们就可检出全部或大部分元素。由于各种元素都有其特征的电子结合能，因此在能谱中有它们各自对应的特征谱线。所以可根据这些谱线在能谱图中的位置即可鉴定元素种类。 一...
