Crystal structure of iron ii oxide
Iron(II,III) oxide is the chemical compound with formula Fe3O4. It occurs in nature as the mineral magnetite. It is one of a number of iron oxides, the others being iron(II) oxide (FeO), which is rare, and iron(III) oxide (Fe2O3) which also occurs naturally as the mineral hematite. It contains both Fe and Fe ions and is sometimes formulated as FeO ∙ Fe2O3. This iron oxide is encountered in the l… WebIron(III) oxide catalysts with varying surface areas and polymorphous compositions were tested in hydrogen peroxide decomposition. The high crystallinity of the particles and the large surface area of the samples result in extraordinary catalytic efficiency, whereas the effect of crystal structure on catalytic performance seems to be negligible ...
