= Iron nanoparticle
{wiki=Iron_nanoparticle}
Iron nanoparticles are small particles of iron that typically range in size from 1 to 100 nanometers. Due to their size, they possess unique physical and chemical properties that differ significantly from bulk iron, including increased surface area, enhanced reactivity, and distinct magnetic properties. These characteristics make iron nanoparticles useful in a variety of applications, such as: 1. **Catalysis**: Iron nanoparticles can act as effective catalysts in chemical reactions, often reducing the energy required for reactions and increasing reaction rates.
