1. EDS可看到由Al-MOF衍生而成的Al位点主要分布在MOF区域中,Al和O分布区域相一致,XPS证明Al-NFM中存在大量Al-O键,27Al MAS NMR证明四、五配位的Al-O不饱和配位点的生成。 图2. Al-NFM的XPS谱图、Raman图谱和27Al MAS NMR图谱(来源:Angew. Chem. Int. Ed.) 2. 在Al-NFM的电催化作用下,以合成2-...
In the as-deposited films the presence of Au clusters with sizes smaller than 1–2nm (not detected by XRD) was demonstrated by XPS. With increasing annealing temperature, Au clustering in the dielectric matrix was also confirmed by XPS, in agreement with XRD results....
Aluminium detected by XPS was all in the oxidized state, and was in the form of hydroxide in the top surface region. Cobalt in the topmost region was in the form of oxyhydroxide, which was easily reduced to the metallic state by Ar + etching. By taking the XPS, XRD and EPMA results ...
Comparative XPS Study of Al2O3 and CeO2 Sulfation in Reactions with SO2, SO2 + O2, SO2 + H2O, and SO2 + O2 + H2O The interactions of Al2O3, CeO2, Pt/Al2O3, and Pt/CeO2 films with SO2, SO2 + H2O, SO2 + O2, and SO2 + O2 + H2O in the temperature range 300-673 K at...
Systematic X-ray photoelectron spectroscopy (XPS), X-ray induced Auger electron spectroscopy (AES), X-ray absorption near edge structure (XANES) and extended X-ray absorption fine structure (EXAFS) studies were undertaken to investigate the electronic structure, chemical states and local geometry of...
The oxidation state of alumina- and titania-supported Ru catalysts has been investigated as a function of reduction temperature, as well as by following the interaction with a methane−oxygen mixture at 773 and 973 K, employing XPS and FTIR techniques. It is found that the chemical behavior ...
