The iron oxidation state in Mg–Al–Fe mixed oxides derived from layered double hydroxides: An XPS study

Mixed oxides with large surface area and high thermal stability can be obtained by thermal treatment of the layered double hydroxides (LDH). Mg–Al–Fe mixed oxide samples with varying Mg/Al ratio and 5 mol.% of Fe were prepared in this way and the iron oxidation state (Feox) in these compounds was studied by X-ray photoelectron spectroscopy (XPS), using a calibration based on the relation of Feo...

Exploring Li substituted O3-structured layered oxides NaLixNi1/3−xMn1/3+xCo1/3−xO2 (x=0.07, 0.13, and 0.2) as promising cathode materials for rechargeable Na batteries

Recent research progress on iron- and manganese-based positive electrode materials for rechargeable sodium batteries

Large-scale high-energy batteries with electrode materials made from the Earth-abundant elements are needed to achieve sustainable energy development. On the basis of material abundance, rechargeable sodium batteries with iron- and manganese-based positive electrode materials are the ideal candidates for large-scale batteries. In this review, iron- and manganese-based electrode materials, oxide...

First principles studies on band structures and density of states of graphite surface oxides

Graphite oxide constitutes carbon network with oxygen atoms both on hexagonal arrangement and the edge sites. Structural and electronic properties for graphite-oxygen complexes have been explored using first-principles total-energy calculations within the local density approximation (LDA). Band structures and density of states for the propose carbon 3D models are reported. A finite energy gap and...
