Valence control of cobalt oxide thin films by annealing atmosphere

Microstructure and optical absorption properties of Au-dispersed CoO thin films

“…The relative integrated intensities of the satellite structure were about 40% and 84% of the main Co 2+ 2p 3/2 and Co 2+ 2p 1/2 peaks. However, the binding energies of Co 2+ 2p 3/2 and Co 2+ 2p 1/2 here are a little lower than those (Co 2+ 2p 3/2 , 780.5 eV; Co 2+ 2p 1/2 , 796.3 eV) in our previous results [23] for the pure CoO film. Fig.…”

“…No other impurities are observed. [23], the former pair of peaks is assigned to the Co 2+ 2p 3/2 and Co 2+ 2p 1/2 electrons and the later one is related to the satellites of the Co 2+ 2p 3/2 and Co 2+ 2p 1/2 electrons in the CoO bond [22,24]. The intense satellite peaks appear at about 5.5 and 6.3 eV beyond the Co 2+ 2p 3/2 and Co 2+ 2p 1/2 peaks.…”

SPR enhanced photocatalytic properties of Au-dispersed amorphous BaTiO3 nanocomposite thin films

“…3% below 165 C, along with a very weak endothermic peak near 103 C, is due to the evaporation of low-boiling point solvent [26]. The second weight loss (7%) with a small endothermic peak at around 197 C could be attributed to the decomposition of organic species [26]. The third weight loss (ca.…”

Reaction and Characterization of Co and Ce Doped Mn/TiO2 Catalysts for Low-Temperature SCR of NO with NH3

“…ions [30]. In addition, two small and broad peaks of Co 2p 3/2 at 782.6 and 785.9 eV are observed like satellite structure peaks [28]. However, it is found that the satellite structure peak don't match the main peak of Co 3?…”

“…By peak-fitting deconvolution, the main Co 2p 3/2 peak could be seperated into two peaks, the lower binding energy one at 779.5 eV is belong to Co 3? [28], which corresponds to compound [Co 2? Co 2 3?…”
