How Can the Stability of Nano Scale ZVI be Improved?
Several strategies can be employed to improve the stability of nano scale ZVI:
1. Surface Coatings: Coating ZVI nanoparticles with materials like polymers, surfactants, or inorganic shells can prevent agglomeration and improve stability.
2. Support Materials: Dispersing ZVI nanoparticles on support materials like activated carbon, silica, or alumina can enhance their stability and prevent loss of reactivity.
3. Alloying: Creating iron-based alloys with metals like nickel or copper can improve the catalytic properties and stability of ZVI nanoparticles.
