Formation

Iron(II) molybdate is created by the reaction of iron(II) chloride or iron(II) sulfate[2] and sodium molybdate.

Applications

FeMoO4 has been used as relatively stable active material for anodes in Li-ion batteries for conversion reaction,[3] as anode material in aqueous supercapacitors due to fast redox reactions[2] and as catalyst for oxygen evolution in alkaline solutions.[4]

Safety

Iron(II) molybdate is toxic and may cause irritation. It should not be released into the environment. Inhalation of dusts should be avoided.
