What are the Challenges Associated with Nano Scale ZVI?
Despite its advantages, there are several challenges associated with the use of nano scale ZVI:
1. Agglomeration: ZVI nanoparticles tend to agglomerate, reducing their effective surface area and reactivity. Stabilizers or surface modifications are often required to prevent this.
2. Environmental Impact: The long-term environmental impact of nano scale ZVI is still under investigation. There are concerns about the potential toxicity of nanoparticles to aquatic life and ecosystems.
3. Controlled Synthesis: Achieving a controlled and uniform size distribution of ZVI nanoparticles is challenging but crucial for ensuring consistent performance in catalytic applications.
