Background and overview ^[1]

Ferric nitrate nonahydrate compound is also known as ferric nitrate, Fe(NO3)3·9H2O=404.02, light purple or off-white monoclinic crystal, easy to deliquesce. The iron nitrate nonahydrate compound has a relative density of 1.684 and a melting point of 47.2°C. It decomposes when heated to 125°C.

It is soluble in water, ethanol and acetone, easily soluble in ether, and slightly soluble in nitric acid. The aqueous solution can be decomposed by ultraviolet rays into ferrous nitrate and oxygen, so it is oxidizing. The iron nitrate nonahydrate compound is made from pure iron filings or iron oxide and concentrated nitric acid. Iron nitrate nonahydrate compound is used as chromatographic analysis reagent, catalyst, mordant and copper coloring agent, and used in medicine.

Application ^[2-3]

CN201911363875.7 discloses a method for preparing graphene, which uses lignin as a raw material, tetrahydrofuran as a modifier, and iron nitrate nonahydrate as a catalyst. The lignin is passed through the modifier and the iron nitrate The nonahydrate compound is treated in a water bath and calcined to obtain graphene. The lignin-like material is straw fermentation residue or straw acid hydrolysis residue. The preparation method of graphene disclosed in the present invention is simple in process and realizes low value-added biomass waste The transformation to graphene, a high value-added product, is of great significance.

CN200710049525.4 discloses a preparation method of magnetic ferroferric oxide nanoparticles supported by carbon nanotubes. It is characterized by adding carbon nanotubes to the ferric nitrate nonahydrate solution, stirring, ultrasonic vibration processing, and then adding some water-soluble polymer aqueous solution, stirring, continuing ultrasonic vibration processing, filtering, drying, grinding, and finally Calcining in an inert atmosphere at a temperature for a certain period of time, and further grinding treatment to obtain carbon nanotubes supporting magnetic ferroferric oxide nanoparticles. The preparation method is highly efficient, low in cost, simple in process, and suitable for industrial production. The obtained carbon nanotube-loaded magnetic ferroferric oxide nanoparticles have high loading capacity, stable structure, uniformity, good dispersibility, and strong binding force with the carbon nanotubes. It can be widely used in magnetic targeting materials, various catalysts, electromagnetic shielding absorbing materials, super capacitor electrode materials and other related functional materials.
