Density functional theory study of water interactions on Mn-doped CeO2(1 1 1) surface
(Elsevier Science, 2014-06)
Spin-polarized density functional theory (DFT + U) periodic calculations have been performed to study water adsorption and dissociation on the 12.5% Mn-doped CeO2(1 1 1) surface. Our results indicated that Mn cation is the ...
Mn-Doped CeO2: DFT+U Study of a Catalyst for Oxidation Reactions
(American Chemical Society, 2013-08-07)
In this work, we performed DFT+U periodic calculations to study the geometric and electronic properties of 12.5% Mn-doped CeO2 solid solution. The doping with Mn allowed some Mn2+ cations to substitute Ce4+ ions into the ...
Improvement of the photocatalytic activity of magnetite by Mn-incorporation
(Elsevier B.V., 2014-02-01)
Mn-incorporated Fe3O4 photocatalysts were prepared by a simple co-precipitation method. Photocatalytic discoloration of Methylene Blue (MB) was used to evaluate the performance of these catalysts. The DSC results have shown ...
Photoluminescence and Magnetism in Mn2+-Doped ZnO Nanostructures Grown Rapidly by the Microwave Hydrothermal Method
(Amer Chemical Soc, 2013-12-12)
Zn1-xMnxO nanostructures were synthesized via the microwave-assisted hydrothermal method, which rapidly produces particles of controlled size and morphology. Samples were analyzed considering the effects of manganese ion ...
Densification and electrical conductivity of fast fired manganese-doped ceria ceramics
(Elsevier B.V., 2005-04-01)
Reactive pure and manganese-doped (5% and 10 at.%) ceria nanosized powders were prepared by the polymeric precursor technique. Physical properties of powder materials were studied by X-ray diffraction, nitrogen adsorption, ...
