Although nanocatalysts enjoy several advantages over conventional catalyst systems; however, isolation and recovery of these tiny nanocatalysts from the reaction mixture is not easy. Conventional techniques (such as filtration) are not efficient because of the nano size of the catalyst particles. This limitation hampers the economics and sustainability of these nanocatalytic protocols. To overcome this issue, the use of magnetic nanoparticles has emerged as a viable solution; their insoluble and paramagnetic nature enables easy and efficient separation of the catalysts from the reaction mixture with an external magnet. We envision designing and preparing magnetically separable nano-catalysts that can be utilized for future challenges on the horizon. We believe, it is only a matter of time before the real prospective of magnetic nanocatalysts are realized and implemented on a far-reaching scale.
