Two similar reasons were proposed: (i) the faster Ag+ release rate from the Fe3O4–Ag hybrid due to the electron transfer from Ag NPs to Fe3O4 NPs; and (ii) the fact that the ionization of Ag NPs in hybrid nanostructure might be accelerated by Fe3+ ions. TEM micrographs of (A) Fe3O4, (B) Fe3O4@SiO2, (C) Fe3O4@SiO2@Ag, and (D) size distributions of Ag Nps (inset shows diffraction pattern of core shell).

Figure 15.1. Magnetite (Fe3O4) Magnetic Black. The synthesis of magnetite NPs is usually provided by alkaline coprecipitation of iron ions Fe2+ and Fe3+ in the ratio 1:2. A shift in the orientation of crystallites can also influence electrode performance, as it would make the electrochemical reaction to proceed asymmetrically. Most intracellular iron was proposed to be contained within the crystals. From Fig. We know that some amount of Fe 3 O 4 with a percent composition of 72.36% Fe will yield 7.5kg of Fe. Chemical synthesis of magnetite Fe3O4 may be described in two principal reactions: the oxidation of ferrous Fe2+-containing salts or the coprecipitation of both Fe2+ and Fe3+ precursors in stoichiometric ratio. Phase composition, morphology, and crystallinity strongly influence the operational behavior of iron electrodes. The first reaction may be performed even without any special oxidizing agent under air atmosphere because of the high oxidizing activity of air oxygen.

The elongated prismatic habits, corresponding to the anisotropic (unequal) development of symmetry-related faces, could occur either because of anisotropy in the growth environment (e.g., concentration and/or temperature gradients) or anisotropy of the growth sites. You're referring to magnetite, Fe3O4. This hybrid nanomaterial appears to be very promising for clean water and food preservation [38]. For example, iron oxide nanoparticles modified with antihuman epithelial growth factor receptor antibody were used for the separation of circulating human breast cancer cells from whole blood [30]. The changes in lattice parameters of the phases should be minimal so as to preserve the mechanical integrity of the electrodes. For the purposes of biomedical applications the uncoated magnetite NPs are not appropriate because of the agglomeration tendency and are often synthesized in the presence of a biocompatible component: organic compound (Bomati-Miguel et al., 2014; Sun et al., 2009), biopolymer of different nature (Wan et al., 2005) including polysaccharides (Daniel-Da-Silva and Trindade, 2011), or otherwise stabilized by the media (El-Sherbiny and Smyth, 2010). Whereas the crystal size distributions of inorganic magnetite and magnetite resulting from dissimilatory iron reduction are typically log-normal, the shapes of the magnetosome crystal size distributions are asymmetric with a sharp high-end cutoff, consistent with a transport-controlled Ostwald ripening process (Eberl et al.
