X-ray photoelectron spectra/ Ti 2p XPS spectrumlow-energy Ar ion bombardmenttitanium oxide single crystalComponents of Ti2+ and Ti3+ as reduced states have appeared, in addition to the Ti4+ state, after ion bombardment at 2 kV. However, although a small amount of Ti3+ has been observed in...
就可以知道与CeO2和TiO2相比,在H2还原后,CeTiOx载体上产生了更多的Ov位。 【XPS能够快速分析出样品中的元素类型,主要原理就是光电效应】 【路易斯酸是给质子,得电子;路易斯碱是给电子,得质子】 Figure S39. Ce 3d (a), and Ti 2p (b) XPS spectra of reduced Rh1/CeO2, Rh1/TiO2, and Rh/CeTiOx sam...
图2-10是一系列Fe掺杂锐钛矿型{001}-TiO2纳米片多级球催化剂的XPS谱图。其中,Fe 2p轨道用于表征催化剂表面Fe元素的掺杂情况。由图2-10A可以看到,{001}-0.1%Fe-AHSs未呈现出明显的Fe元素的特征衍射峰且未检测到表相Fe元素的存在。进一步结合该催化剂的元素组成分析结果(表2-4),EDX能谱计算得到的体相组成nFe...

Corrections of the Ti 2p XPS spectra with the relevant energy losses obtained by EELS allow a consistent interpretation of the Ti photoemission peak structure and a considerable improvement in the quantification of the corresponding Ti compound.
Survey spectra (Fig. S11) revealed the presence of Ti, C, O, and F in Ti3C2Tx-SL and Ti3C2Tx-ML MXenes and the additional presence of Mo in the spectrum of Mo2TiC2Tx-SL MXene. The F peak was attributed to the HF etchant. High-resolution Ti 2p XPS spectra of Ti3C2Tx-ML (...
