Oct 1, 2019 · Herein, the phase changes of commercial mesoscopic CoO (particle size ˜1 μm) and nanosized CoO (20–50 nm particle size), the latter prepared by vacuum reduction of …

Dec 1, 2016 · Co 3 O 4 bulk and surface state was characterized by operando XANES and NAP-XPS. Easy surface reduction in pure CO (∼100 °C) is via reaction with lattice oxygen. Fast …

Feb 16, 2022 · Extended X-ray absorption fine structure spectroscopy (EXAFS) analysis shows that the CoO bilayer characterized in ultrahigh vacuum is not formed under the conditions …

Here, various cobalt-based compounds, differing in crystal structure, ligands surrounding the central metal ion and morphology, have been studied by soft X-ray absorption spectroscopy …

In this work we investigate the electronic structure of CoO using resonant inelastic X-ray scattering (RIXS) spectroscopy with selective excitation energies around the Co 2p thresholds. …

Targeted synthesis of acetic acid (CH3COOH) from CO2 photoreduction under mild conditions mainly limits by the kinetic challenge of the C−C coupling. Herein, we utilized doping …

Dec 1, 2018 · Herein, the phase changes of commercial mesoscopic CoO (particle size ˜1 μm) and nanosized CoO (20–50 nm particle size), the latter prepared by vacuum reduction of …

Jan 25, 2000 · Silica-supported cobalt catalysts have been investigated by soft X-ray absorption techniques. Soft X-ray absorption spectra were collected at the Co L II,III edge during in situ …

Jun 16, 2017 · The pressure-response of the Co-O bond lengths and the spin state of Co ions in a hybrid 3d-5d solid-state oxide Sr 2 Co 0.5 Ir 0.5 O 4 with a layered K 2 NiF 4 -type structure …

We develop a general procedure to analyse the pre-edges in 1s x-ray absorption near edge structure (XANES) of transition metal oxides and coordination complexes. Transition metal …
