“…Zhang et al prepared the carbon encapsulated iron nanoparticles by DC arc discharge and found that the shell contained C, Fe, and O elements and its structure consisted of three parts; that is, the inside part was nongraphite, the middle one was incomplete graphite, and the outside one was amorphous carbon [15]. Kim et al employed the process of chemical vapor condensation to prepare the carbon-coated Fe nanocapsules, and the shell was a double layer structure, that is, Fe 3 C and graphite layers [16]. Zhang et al synthesised the core-shell-shell composite submicrospheres (Fe 3 O 4 @SiO 2 @MnO 2 ) by homogeneous precipitation of MnO 2 on Fe 3 O 4 @SiO 2 spheres, which were prepared by a modified sol-gel method in the presence of Fe 3 O 4 particles, and the submicrospheres showed superparamagnetic property (Ms value 29.41 eum/g), high activity of chemical adsorption, and good stability for the decolouration of organic dye [17].…”

“…The non-metallic shell prohibits the agglomeration of metallic nanopowders to a large extent. In addition, the salt layer acts as a barrier against oxygen or other gases in the atmosphere which might otherwise react with the metal [1,2]. Chemical vapor condensation (CVC) is one of the major techniques used in the production of nano-powders.…”
