Synthesis of core–shell Fe3O4@SiO2@MS (M=Pb, Zn, and Hg) microspheres and their application as photocatalysts

One-pot synthesis and characterization of bifunctional Au–Fe3O4 hybrid core–shell nanoparticles

“…Individually, Au nanoparticles have been scrutinized for advanced functionalities in the areas of single electron capacitors [15], thermal transport [16], fluorescent enhancement [17] and nonlinear optical materials [18], among others. In comparison, Fe 3 O 4 nanoparticles are under investigation for promising biomedical applications [14], microwave properties [19], ferrofluids [20] and photocatalysis [21].…”

Facile preparation of amidoxime-functionalized Fe3O4@SiO2-g-PAMAM-AO magnetic composites for enhanced adsorption of Pb(ii) and Ni(ii) from aqueous solution

“…Therefore, the Freundlich isotherm can be applied for non-ideal adsorption on multilayer adsorption and heterogeneous surfaces in nature. 32 Compared with other magnetic adsorbents, the adsorption capacities on Fe 3 O 4 @SiO 2 -g-PAMAM-AO for Pb(II) and Ni(II) are higher than those for Pb(II) and Ni(II) sorption on other related materials, as listed in Table 3. Fe 3 O 4 @SiO 2 -g-PAMAM-AO with such a high ability for Pb(II) and Ni(II) sorption exhibits a potential for real applications in the removal of Pb(II) and Ni(II) from large volumes of aqueous solutions.…”

Synthesis and characterization of Fe/C core–shell nanoparticles

“…In addition, carbon exhibits good hydrophilic and biocompatible properties, which makes it possible to load other functional molecules such as enzymes, antigens and proteins [3]. Therefore, carbon-encapsulated magnetic nanoparticles are promising candidates for applications in magnetic resonance imaging (MRI) [4], ultrahigh-density magnetic recording media [3,5], integrated diagnosis and therapeutics [6], clinical drug delivery [2], catalysis [7], environmental protection [8,9], and electromagnetic (EM) wave absorption [10], etc.…”
