Iron(III) nitrate nonahydrate

Iron(III) nitrate nonahydrate is an inorganic iron salt that is used as an iron precursor for the synthesis of iron oxide nanoparticles.

A variety of organically templated iron phosphates, of interest because of their rich crystal chemistry and their ability to absorb large molecules in their micropores,were prepared using this compound.[1]

Iron(III) nitrate nonahydrate can be used as:

• A catalyst in the oxidation of 1^o, 2^o, and benzylic alcohols to their corresponding carbonyl compounds in the presence of heteropoly acids.
• A promoter in the synthesis of polycrystalline boron nitride nanotubes (BNNTs) by a ball milling-annealing method.

It can also be used to synthesize:

• Iron-doped mesoporous silica used as an efficient catalyst for the degradation of rhodamine B dye under acidic conditions.
• Iron(III)-doped titania nanoparticles by modified sol-gel method.
