关于Cu的元素价态XPS、LMM,LVV? - 盖德问答
Cu的XPS文献较多 讨论 LMM的也很多 不需要拘泥于你本专业的文献 可以广泛参考。 至于你说的 923.8和917.8相差很大的问题 可能因为矫正的问题和仪器的问题 有一定的差别是正常的 不过 …
铜 | Thermo Fisher Scientific - CN
主要采集 Cu2p 峰及 Cu LMM 峰。 与 Cu2p 峰相比,Cu LMM 峰观察到的化学位移更大。 仅采集 Cu2p 可能难以区分化学态。 长期暴露于 X 射线或离子轰击会使二价铜还原,Ar 离子团簇模式 …
X-ray Photoelectron Spectroscopy (XPS) Reference Pages
The Cu LMM peak shape (in addition to the Auger parameter and Cu 2p3/2 peak position and shape) can also be useful in determining Cu chemical states. It is particularly useful when …
Copper | Periodic Table | Thermo Fisher Scientific - US
Bigger chemical shifts observed for Cu LMM compared to Cu2p. Chemical state differentiation can be difficult with XPS only. Long X-ray exposure or ion bombardment can reduce or …
X-ray Photoelectron Spectroscopy (XPS) Reference Pages
X-ray photoelectron spectroscopy (XPS or ESCA) curve fitting procedures, reference materials and useful notes are listed here to provide a starting point for the consistent interpretation of …
XPS测试结果Cu LM2峰分析 - 催化 - 表征 - 小木虫论坛-学术科研 …
大家好,最近做了一个碳载cu基催化剂,测xps的时候结果中cu lm2峰值在570ev左右,查了很多文献后发现横坐标都是kinetic energies ,而我拿到的数据中横坐标是binding energy,不知您没 …
【求助】CuXPS的LMM能谱的分析 - 经验共享 - 分析测试百科网
我的铜基催化剂本来扫出来的LMM谱图在550-600ev之间,按照论坛里的一个帖子提示我将550-600 eV结合能转化成俄歇电子动能,即1486.6-BE,这样就转换到900-930 eV 俄歇谱电子动能 …
【求助】Cu XPS 中铜的价态区分 - 经验共享 - 分析测试百科网
XPS确实很难区分Cu(0)和Cu(I),用俄歇谱来区分是可以做到的。 如果lz需要,给个邮箱,我把Cu的XPS图谱发给你,可以按照图谱数据区分铜的零,一,二价 whitesheep (2016-2-17 …
Copper – HarwellXPS Guru
When analysing copper it is imperative that you record the Cu LMM auger as well as the Cu 2p region. This is because the difference between Cu 0 and Cu I XPS spectra is very slight, and …
a) Cu 2p XPS, b) Cu LMM Auger, and c) I 3d XPS spectra of Cu, …
X-ray diffraction (XRD) patterns of Cu catalyst (Supporting Information, Figure S3a) show both characteristic diffraction peaks of Cu and Cu 2 O, indicating that the Cu nanoparticles are...
