Further evidence for the composition of the product was inferred from the X-ray photoelectron spectroscopy (XPS, Thermo ESCALAB 250XI, USA), using an ESCALab MKII X-ray photoelectron spectrometer with Mg-KαX-rays as the excitation source. The flat band potentials of the samples were ...
35.针对前述制备方法得到的无定形cu2o/生物质碳催化剂,用x射线光电子能谱(xps, thermo scientific k-alpha)分析其化学成分,使用了al kαx射线源(hν=1486.6ev)。结果如图2所示。从图中可以看出,本实施例制备的催化剂在结合能为931.6ev和951.8ev处有两个明显的峰,分别对应于cu 2p1/2和cu 2p3/2,图中的o...
Mixed silver–copper oxide Ag2Cu2O3 was investigated by a combination of physicochemical techniques, including X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), and temperature programmed reaction (TPR). The catalytic properties of Ag2Cu2O3 in the reaction of CO oxidation were ...
