“…In Fig. 4c, In ZnFe 2 O 4 @SiO 2 @ APTES, the bands in the range of 2879 cm −1 correspond to the bending vibration of CH 2 confirming the attachment of APTES chain molecules 48,49 . The bands at 1442 cm −1 correspond to NH due to the deformation of the hydrogen-bonded amine groups respectively.…”

In this paper, we report the synthesis of ZnFe2O4@SiO2@APTES@DHBS-Cu as a novel magnetic nanocatalyst, in a mild and green environment. The structure of the described magnetic compound was characterized by different physicochemical techniques including XRD, EDS, AAS, SEM, FT-IR, X-ray elemental mapping, TGA, and VSM analyses. The prepared magnetic nanoparticles exhibit excellent catalytic activity in synthesizing bis (pyrazolyl)methanes and oxidation of sulfide derivatives under green conditions. The heterogeneous nature of the catalyst was confirmed via the hot filtration experiment. Further, ZnFe2O4@SiO2@APTES@DHBS-Cu showed high efficiency and reusability that could be reused for at least five consecutive runs.

“…As shown in the figure, the band at 592 cm-1 is attributed to Fe-O bending vibration mode [7]. The strong absorption band at 1072 cm-1 is relate to the asymmetrical stretching vibration of Si-O-Si [5,6].The presence of C-H groups of 3-aminopropyltriethoxysilane were established by stretching vibrations at 2800~2900 cm-1 in the FTIR spectrum [8,9]. These results indicated that the surface of ferrous-ferric oxide nanoparticles was modified with silicon dioxide-NH2 groups as well.…”

Engineered magnetic nanoparticles have great potential in environmental since they are aiding the separation of a contaminant from aqueous solution by using an external magnetic field. Therefore, in this study, nano sized ferrous-ferric oxide, and ferrous-ferric-silicon dioxide-NH2 were synthesized using a co-precipitation and sol-gel methods, respectively. The nanomaterial was used as an adsorbent for the removal of lead ions from aqueous solution. The nanomaterial was characterized by using TEM and FT-IR techniques. Batch adsorption experiment at room temperature were applied to determine the optimum contact time to remove heavy metal ions from aqueous solution. Consequently, time dependency study showed that the highest removal occurred about two hours contact between adsorbent and lead ions. The removal capacity of the nanomaterial adsorbent was about 78%.
