Recent Developments in Hybrid Iron Oxide-Noble Metal Nanocatalysts for Organic Reactions

Abstract A review of recent developments in the synthesis of hybrid iron oxide–noble metal nanocomposites and their application to various organic reactions is presented herein. Focus is placed on various strategies for achieving (1) Au nanoparticles (NPs) on Fe 3 O 4 @polymer catalysts, (2) optimized dispersion and stability of Fe 3 O 4 /Pd catalysts, (3) Au NPs supported on Fe 2 O 3 –graphene oxide hybrid nanosheets and (4) rose-like Pd–Fe 3 O 4 hybrid nanocomposite-supported Au nanocatalysts. Further application of such hybrid nanocomposites as catalysts for various organic reactions is discussed in brief.
