Fe2O3 vs. Fe3O4

Fe2O3, also known as iron (III) oxide or ferric oxide, consists of two iron atoms bonded to three oxygen atoms. It is commonly found in nature as the mineral hematite and has a reddish-brown color. Fe3O4, also known as iron (II,III) oxide or magnetite, consists of two iron atoms bonded to four oxygen atoms.

Fe3O4

Fe 3 O 4 is the chemical formula of Iron (II, III) oxide which has four oxygen atoms, and three iron atoms. The bond formation between iron and oxygen depends on the difference in electronegativity between them. Iron (Fe) is metal and oxygen (O 2) is non-metal. The bond between them is called an Ionic bond.

In Situ Synthesis of α-Fe2O3/Fe3O4 Heterojunction …

In this work, a holey nanorod Fe 2 O 3 /Fe 3 O 4 heterojunction photoanode with oxygen vacancies was fabricated using a rapid and facile flame reduction treatment. Compared with pure Fe 2 O 3, the water oxidation performance of the Fe 2 O 3 /Fe 3 O 4 photoanode is improved by ninefold at 1.23 V RHE.
