General description

Iron(III) nitrate nonahydrate is an inorganic iron salt that is used as an iron precursor for the synthesis of iron oxide nanoparticles.
We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Green Chemistry. This product has been enhanced for catalytic efficiency. Click here for more information.

Application

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.
Iron(III) nitrate nonahydrate can be used as:     
  • A catalyst in the oxidation of 1o, 2o, 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.

All real processes, be they chemical, mechanical or electrical, are thermodynamically irreversible and therefore suffer from thermodynamic losses. Here, we report the design and operation of a chemical reactor capable of approaching thermodynamically reversible operation. The reactor was employed for
