XPS studies of superconducting Mo–Ru–Rh–Pd alloy

Ternary PdMoP Nanoparticles Anchored on Boron–Nitrogen Functionalized CNTs for High-Efficiency Formic Acid Electrooxidation

“…In other words, the core-level of Pd shifts down with respect to the Fermi level of Pd, corresponding to a downshift of the d-band center of Pd due to its alloying with Mo and P, thus indicating that Mo is doped into the Pd lattice. This lattice strain effect in the PdMoP 0.01 /OB-CNT-N catalyst is consistent with the reported behavior of platinum group metal (PGM) alloys. , A suitable downshift of the d-band center can weaken the adsorption of both reactants and intermediates, improving the electrooxidation of formic acid. Simultaneously, the change in the binding energy of palladium is reasonable evidence that its electronic structure is adjusted.…”

Organometallic Clusters As Precursors for Metallic Nanoparticles: Effect of Cluster Size, Ligand Set, and Decomposition Method

“…X-ray photoelectron spectroscopy (XPS) analysis of the NPs obtained from 14 (Figure ; the Si 2p signal at 103.4 eV was used as a reference for the binding energies, as the Ru 3d and the C 1s lines overlapped) showed the presence of Ru (280.7), RuO 2 (283.9 eV), Os (Os 4f 7/2 : 51.2 eV), and OsO 2 (54.2 eV) . These indicated that the NPs were osmium−ruthenium bimetallic particles with well-defined composition, and they have undergone oxidation upon exposure to air . The osmium-to-ruthenium ratio is ∼8.5:1 (based on elemental analysis), and may be due to the loss of the metals as their volatile tetroxides (boiling points of 130 and 40 °C, respectively).…”

Transformations of biomass-based levulinate ester into γ-valerolactone and pyrrolidones using carbon nanotubes-grafted N-heterocyclic carbene ruthenium complexes

“…The Ru 3 d XPS shows a peak at binding energy of http://engine.scichina.com/doi/10.1016/j.jechem.2019.01.007 285.8 eV closing to the C1 s peak at 284.6 eV from the CNT support ( Fig. 5 a), which interferes the accurate investigation of the Ru oxidation state [41] . While, Ru 3 p XPS was divided into two peaks at the binding energy of 464.2 eV (indexed to Ru 3 p 3/2 ) and 486.2 eV (indexed to Ru 3 p 1/2 ), indicating the presence of divalent Ru in CNT-Ru-1 ( Fig.…”
