Iron(II) molybdate is an inorganic compound with the chemical formula FeMoO4.[2]
Synthesis
Iron(II) molybdate is prepared by the reaction of iron(II) chloride or iron(II) sulfate[3] and sodium molybdate.
Due to its very low aqueous solubility, iron(II) molybdate precipitates out as a brown powder from the above reactions, which can then be obtained by filtration.
Applications
FeMoO4 has been used as relatively stable active material for anodes in Li-ion batteries for conversion reaction,[4] as anode material in aqueous supercapacitors due to fast redox reactions[3] and as catalyst for oxygen evolution in alkaline solutions.[5]
Safety
Iron(II) molybdate is toxic and may cause irritation. It should not be released into the environment. Inhalation of dusts should be avoided.
