The XPS spectra of CeO2/5%Cu prepared using wet impregnation method

The dataset includes XPS spectra of CeO2/5%Cu catalyst sintered under air atmosphere. Samples were produced using aqueous soft chemistry methods and incipient wettness impregnation using nitrate solution. The XPS spectra were collected for all species. Description of the procedure: X-ray Photoelectron Spectroscopy analysis (XPS) was performed using X-ray photoelectron spectrometer Omnicron NanoTechnology with 128-channel collector. XPS measurements were undertaken in ultra-high vacuum conditions, below 1.1x10-8 mbar. Photoelectrons were excited by an Mg-Kα X-ray source with X-ray anode operated at 15 keV and 300 W

本数据集包含空气气氛下烧结的二氧化铈/5%铜催化剂（CeO₂/5%Cu catalyst）的X射线光电子能谱（X-ray Photoelectron Spectroscopy, XPS）。样品通过水相软化学法结合硝酸盐溶液初湿浸渍法制备。所有测试物种均采集了XPS能谱。实验流程说明如下：采用搭载128通道收集器的奥米克朗纳米科技（Omnicron NanoTechnology）X射线光电子能谱仪开展XPS分析。测试在超高真空环境下进行，真空度低于1.1×10⁻⁸毫巴。光电子由Mg-Kα X射线源激发，该X射线阳极的工作参数为15 keV与300 W。
