Oxid železitý (Fe 2 O 3) je sloučenina trojmocného železa s kyslíkem. Limonit (hnědel) je hydratovaný oxid železitý. Vyskytuje se nejčastěji v α krystalické modifikaci jako hnědočervený prášek. V přírodě se vyskytuje jako minerál hematit.V této fázi má klencovou strukturu (romboedrickou), antiferomagnetické vlastnosti a při zahřívání na 675 °C přechází na ...
Here, we report Fe2O3/N-doped carbon (Fe2O3/CN) composites via one-step facile calcination process using FeOOH and PANI as precursor. The results show that N-doped carbon is helpful to enhance the electrochemical properties of Fe2O3. N-doped carbon not only enhances the conductivity of Fe2O3 electrode, but also alleviates the volume expansion of …
