What are the Challenges in Using Magnetic Catalysts?
Despite their advantages, magnetic catalysts face several challenges:
- Stability: Magnetic nanoparticles can aggregate over time, leading to a loss of surface area and catalytic activity. Surface modification techniques are often required to maintain stability. - Leaching: Metal leaching can occur, especially in acidic or basic conditions, leading to contamination of products and loss of catalyst material. - Scalability: The synthesis of magnetic nanoparticles with uniform size and shape can be challenging, which affects the reproducibility and scalability of catalytic processes.
