“…These attributes enhance its application value and broaden its potential uses. 12 Recently, most researchers believe that it is crucial to stabilize the readily formable benzylic carbocation of lignin where condensation reactions are calculated to be significantly more favorable than cleavage of the C-O linkages in lignin. 13 Through stabilization of the benzylic carbocation, β-O-4 linkages of lignin could be preserved for high value utilization.…”

Once released into the environmenOnce released into the environment, engineered nanomaterials can significantly influence the fate of organic contaminants. So far, nothing is known about the capability of composite nanomaterials to accelerate the abiotic transformation processes of organic pollutants that are relevant to the environment. Under benign conditions, it is possible to successfully sulphonate recycled commercial polystyrene to boost its surface functionalities and enable the manufacturing of composites through interactions between the surface functional groups and nanoparticles. The porous R-Fe2O3 nanorods were successfully obtained by calcining the R-FeOOH precursors at 300°C for 2 h. In this study, a photocatalytic system composed of α-Fe2O3 and SPS was applied in 1, 1, 2 trichloroethane degradation. Hence, the α-Fe2O3/SPS composite has great potential for sustainable and efficient photocatalytic disinfection applications. The structural and magnetic properties of R- Fe2O3 nanoparticles were confirmed using the results of morphology tests including Fourier-transform infrared spectra, particle size analysis, and transmission electron microscope.

“…[21] Finally, the removal of dye pollutants from aqueous matrices by various adsorbents and composites has been recently reviewed. [22][23][24] Surfactants are additionally used as nanosorbents because they have either anionic or cationic head groups attached to long tail of hydrocarbon chains. [25] The adsorption efficiency of adsorbent-loaded surfactant is generally produced by the electrostatic interaction between surfactant ionic groups and the charged surface.…”

Design and assembly of novel nanocomposites with multi‐purpose activities including efficient adsorption behavior toward different pollutants and microbial growth inhibition of various active biological species is a challenging aspect. Therefore, the current study is devoted to fabricating a novel nanocomposite of mixed metal oxides (ZrO2 and SiO2) with magnetite (Fe3O4) and cationic surfactants (cetyltrimethyl ammonium bromide [CTAB] and dodecyltrimethyl ammonium bromide [DoTAB]) via a solvent free microwave methodology to yield ZrSiO4 NPs‐CTAB@Fe3O4 NPs‐DoTAB. The as‐prepared nanocomposite was characterized by SEM to confirm the existence of homogeneous particles (~32.45 nm). The chemical structure of nanocomposite was also confirmed from the energy dispersive X‐ray spectroscopy (EDX), Fourier‐transform infrared spectroscopy (FTIR), and X‐ray diffraction (XRD) analyses. The surface area of this nanocomposite was also determined by the Brunauer‐ Emmett‐ Teller (BET) method and found to correspond to 6.319 m2 g−1. Remediation of Azorubine E122 food dye was optimized in the presence of a number of controlling parameters. The maximum adsorption capacity was characterized as 66.55 mg g−1 using 50 mg nanocomposite at 20 min. Kinetics and isotherm modeling evaluations referred to the best fitting with pseudo‐second order and Freundlich model, respectively. The antibacterial activity of ZrSiO4 NPs‐CTAB@Fe3O4 NPs‐DoTAB nanocomposite was assessed against Escherichia coli ATCC® 25922™ and Staphylococcus aureus ATCC® 25923™, and the collected data proved efficient growth inhibition (p < 0.05) at considerably low concentrations of the investigated nanocomposite. Therefore, the evaluated ZrSiO4 NPs‐CTAB@Fe3O4 NPs‐DoTAB nanocomposite was concluded to afford excellent antibacterial activity and efficient magnetic removal behavior of organic dyes. Hence, it is recommended as a talented material for purification of water resources containing multi‐chemical and biological pollutants as well. Finally, this study is expected to open new prospects for manufacturing other new nanocomposites with the aim of future applications in the removal of different chemical pollutants as well as viruses and bacteria.
