This study investigated the photo-degradation of methyl orange (MO) as a type of azo dye using a CuO/α-Fe2O3 nanocomposite. A CuO/α-Fe2O3 powder with a crystalline size in the range of 27-49 nm was successfully prepared using simple co-precipitation along with a sonication method. The characterization of the synthesized sample was done via XRD, FE-SEM, EDS, FTIR and DRS analyses. The Tauc equat...

In order to obtain competitive strontium ferrite sintered magnets, SiO2 and CaO are added avoid exaggerated grain growth. Besides favoring proper densification, these additives prevent the collapse of coercivity associated However, may lead slight decreases in density formation paramagnetic α-Fe2O3 that hampers magnetization. Here, with motivation simplifying production process, we present a st...

Fe2O3 and Fe2O3:Ge nanofibers (NFs) were prepared via electrospinning thoroughly characterized several techniques in order to investigate the effects produced by germanium incorporation nanostructure crystalline phase of oxide. The results indicate that reference NFs consist interconnected hematite grains, whereas NFs, constituted finer elongated nanostructures developing mainly along their axi...
