Fabrication and electrochemical properties of α-Fe2O3 nanoparticles

Transition from single crystalline FeCO3 to layered and ordered nanostructured α-Fe2O3

“…3(e)) are characteristic for the FeO 6 octahedrons vibrations in α-Fe 2 O 3 [17,18]. The weak band at 1048 cm À 1 is attributed to some residual sulfate groups, while the 1631 cm À 1 -centered band belongs to the H-O-H vibrations.…”

Electrochemical properties of submicron cobalt ferrite spinel through a co-precipitation method

“…Similar to transition-metal oxides [15][16][17][18][19][20], the reversible electrochemical reaction mechanism of lithium with CoFe 2 O 4 entails for the most part of a displacive redox reaction. Due to the discharge reaction is thermodynamically feasible, the sample exhibits a high first discharge capacity.…”

Production and characterization of the nanostructured hollow iron oxide spheres and nanoparticles by aerosol route

“…Nanomaterials have attracted growing attention because of their size dependent novel magnetic, optical, electrical, and other physicochemical properties that give an opportunity to use them various significant potential applications [1][2][3][4]. Recently, it is realized that functionality and features of the nanostructures can be controlled by not only their size but also the shape of nanomaterials, so the production of nanostructures with desired morphology, orientation and dimensionality is also a currently a major focus for development of nanoscience and nanotechnology [5][6][7][8].…”
