The XPS data in the C 1s region (Figure 3 c) is quite complex, showing a total of seven components including peaks assigned to the Ru 3d photoelectrons, at 280.8 eV (Ru 3d 5/2 of …

2015年9月22日 · X-ray photoelectron spectroscopy (XPS) utilising monochromatic Al Kα radiation has been employed to study metallic ruthenium and the catalytically and technologically …

2023年3月14日 · To probe the evolution of electronic structure at the surface of the catalysts, we carried out quasi in situ XPS studies to examine the potential-dependent oxidation of O 1s and …

Ruthenium (Ru) has been theoretically considered a viable alkaline hydrogen evolution reaction electrocatalyst due to its fast water dissociation kinetics. However, its strong affinity to the...

2015年11月15日 · Ru nanoparticle 3d, 3p, and 3s core XPS spectra were found to be composed of three symmetric components. The first component, Ru1, is due to zerovalent R, while …

2024年1月1日 · Due to the signal overlapping of Ru 3d and C 1s at the binding energy of 285 eV, the high-resolution XPS spectra of Ru 3p were analyzed to further prove the coexistence state …

In order to unravel the coexistence of Ru and RuO 2 , we further analysed the Ru species by XPS (Fig. 3c). The peaks at 461.9 eV and 484.1 eV are assigned to metallic Ru, while those at 463.7...

An excellent communication in Surface and Interface Analysis from David Morgan [1] presents fitting parameter values for the Ru 3d and Ru 3p peaks for Ru metal, RuO2, RuCl3, Ru (NO) …

X-ray photoelectron spectroscopy (XPS) characterization was performed to confirm the hydrous nature of the as-synthesized RuO2 nanoparticles. The survey XPS spectrum from our sample …
