dc.description.abstract | A family of Fe3O4/MnO hybrid nanocrystals differing in heterojunction structure and number of MnO domains were synthesized through the seed-mediated growth process of MnO at the surface of Fe3O4 nanocrystal. In this process, the resulting heterostructures, including core/shell, dumbbell-like, and flowerlike structures, were found to be largely influenced by the size of initially injected Fe3O4 seeds. The further transformation of Fe3O4/MnO heterodimer through a nanoscale etching process within silica nanosphere generated the nanoreactor framework composed of a superparamagnetic Fe3O4 nanocrystal, a functionalized cavity with a catalytically active Mn3O4 layer, and a porous silica shell. The newly developed nanoreactor successfully catalyzed the cyanosilylation reaction of aromatic aldehydes in a size selective manner and could be recovered magnetically and reused without loss of catalytic activity even after ten successive cycles. | - |
