Description

General description

Reduced iron powder, also known as iron sponge, is a fine powdered form of iron that is commonly used in chemical synthesis processes. It is produced by the reduction of iron oxide in a controlled environment, typically through the use of hydrogen or carbon monoxide gas.




In chemical synthesis, reduced iron powder can be employed as a reducing agent, catalyst, or precursor in a wide range of reactions. It is commonly used to convert organic functional groups, such as aldehydes, ketones, and nitro compounds, into their corresponding reduced forms. It is also known to facilitate hydrogenation reactions.




Reduced iron powder finds applications in the production of iron-based catalysts, magnetic materials, pigments, and metal alloys. It is commonly used in pharmaceutical synthesis, organic chemistry, and industrial manufacturing. It is important to handle reduced iron powder with care due to its potential reactivity with moisture and oxygen, which may cause oxidation and result in changes to its properties. Proper storage and handling procedures should be followed to maintain its quality and prevent unwanted reactions.

Application

• Sodium-Ion Batteries: Research demonstrated the use of iron-based Na(4)FeV(PO(4))(3) nanoparticles in pine pollen derived carbon matrices as a cost-effective cathode for sodium-ion batteries, emphasizing sustainable energy solutions and materials chemistry (Wang et al., 2024).
