Magnetically Recyclable Nanocatalysts: Eco-friendly Solutions for Green Catalysis

摘要

In the last decades, there has been an escalating concern about environmental protection, which motivated the quest for novel cost-effective sustainable catalytic technologies. With the advent of Nanoscience, magnetic nanomaterials such as transition metal nanoferrites, conquered new horizons in Green Catalysis. By combining the intrinsic advantages of nanosize materials with the easy recovery by magnetic separation, magnetic nanoparticles unlocked the gateway to a new generation of recyclable nanocatalysts. This work provides an overview of our recent breakthroughs in the design of magnetically recyclable nanocatalysts. We will start by presenting their application as catalyst supports for the immobilization of (a) a metal complex with high catalytic efficiency in oxidation reactions and (b) gold nanoparticles catalytically active in the 4-nitrophenol reduction. In a distinct approach, superparamagnetic nanoferrites were used as intrinsic catalysts in the degradation of a dye.
