Abstract

Abstract: A novel, facile and straightforward approach is developed to fabricate magnetic carbon nanoreactor consisting of multi‐functional double‐layered shell, large void space, tailored dimensions, and high surface area. The presented strategy involves unexampled one‐pot combination of gas‐bubble assisted Ostwald ripening method and polymerization of resorcinol‐formaldehyde. The inner Fe3 O4 layer imparts the nanoreactor with superparamagnetic character and thereby, simplifies its separation from the reaction media. The outermost carbon shell protects the inner layer from harsh external environment and also provides additional sites for metal decoration. The internal cavity of the nanoreactor was easily filled with copper metal. Thus, due to the presence of large number of catalytic active sites and the advantages of hollow architecture, Cu@Fe3 O4 ‐C exhibited excellent catalytic activity with perfect reusability for the oxidative bromination reaction. This work indicates that magnetic porous carbon nanoreactor could provide an ideal support for the immobilization of metals in the urge to develop highly efficient catalysts. Abstract : A new and facile approach is designed to synthesize magnetic carbon double‐shelled nanoreactor based on template‐free gas bubble assisted Ostwald ripening process. The inner cavity and outer shell of the nanoreactor is filled with copper metal to form Cu@Fe3 O4 ‐C which exhibited excellent catalytic activity and reusability for the confined oxidative bromination reaction.
