Preparation of copper-cobalt oxide spinels by thermal decomposition of copper-cobalt basic nitrate mixed crystals Copper-cobalt oxide spinels with a common formula Cu x Co 3 x O 4 (0≤ x ≤1.0) have been prepared by thermal decomposition at 350° C in air of single... K Petrov,L Markov...
Cobalt forms two well-defined binary compounds with oxygen: cobaltous oxide, CoO, and tricobalt textroxide, or cobalto-cobaltic oxide, Co3O4. The latter contains cobalt in both +2 and +3 oxidation states and constitutes up to 40 percent of the commercial cobalt oxide used in the manufactur...

cobalt oxide nanocatalyst for OER, published to that time, by a PLFL of Co microscale powder in water30. The OER activity of the best CoFe2O4/CoO catalysts in this study is higher than that reported previously by McCroryet al. for a CoFeOxcatalyst11. We reach an overpotential of 0....
Synthesis, characterization, and investigation of optical and magnetic properties of cobalt oxide (Co3O4) nanoparticles Spinel-type cobalt oxide (Co 3 O 4 ) nanoparticles have been easily prepared through a simple thermal decomposition route at low temperature (175掳C) using... S Farhadi,J Safa...
The current synthetic strategy has good prospects for the future production of other transition-metal oxides particles with hollow interior. Furthermore, double-shell cobalt oxide (CoO) hollow particles could also be obtained through calcinating corresponding CoO hollow particles. The magnetic measurements...
Monodispersed cubic crystals (0.1 μm in edge length) of cobalt(II,III) oxide, Co 3O 4, have been obtained by heating cobalt acetate solutions (10 3–10 2 M) at 100°C for a few hours. Bubbling of oxygen prior to aging was found to greatly increase the yield in Co 3O 4. No ...
The structural and optical properties of cobalt-doped zinc oxide (Co-doped ZnO) nanoparticles have been investigated. The nanopowder with Co concentrations up to 5 at% was synthesized by a co-precipitation method. The physical structure and the chemical states of the Co-doped ZnO were characteriz...
Structure, magnetism, and dissociation energy of small bimetallic cobalt-chromium oxide cluster cations: A density-functional-theory study We study CoxCryOm+(x+y=2, 3 and 1≤m≤4) clusters by means of density-functional-theory calculations. It is found that the clusters grow preferentially throu...
