Magnetic Nanoparticles: Green and Environment Friendly Catalyst for Organic Transformations
- 67 Downloads
Catalysis by nanoparticles seems an attractive and sustainable alternative of conventional catalyst systems in organic transformations because of their small size and larger reactive surface to volume ratio with higher potential for selectivity. Among the nanocatalysts, magnetic nanoparticles or magnetic core–shell nanoparticles have gained a significant place due to their paramagnetic nature facilitates the separation of catalyst through the use of an external magnet which makes the recovery of the catalyst easier and prevents loss of catalyst associated with conventional filtration or centrifugation methods. The possibility of reusability and milder reaction conditions are additional advantages of nanoparticle catalyzed organic transformations.
