“…CTAB with the positive charge can be attracted to the NiO surface with the negative charge to form a bilayer. At the same time, the hydroxyl groups of the CTAB can form hydrogen bonds with the oxygen atoms on the surface of the NiO, further enhancing the binding between them [25]. When the doping concentration of the CTAB gradually increases, the CTAB molecules continuously adsorb on the crystal face of the NiO to form an organic phase, which inhibits the growth of the NiO crystal, and resulted in the decrease of the grain size and crystallinity of the NiO and a slight lattice distortion [26,27].…”

A series of mesoporous NiO catalysts with high specific surface area were prepared by a simple hydrothermal method and modified by cetyltrimethylammonium bromide (CTAB) as the crystal structure directing regent. The characterization with SEM, XRD, BET, and H2-TPR results demonstrated that the introduction of CTAB effectively improved the dispersion, specific surface area, and pore volume and redox ability of NiO, and thus exposed more active sites. Meanwhile, the NiO catalyst with a CTAB/NiSO4·6H2O molar ratio of 2/3 exhibited the better catalytic ozonation performance of toluene, formaldehyde, methanol, and ethyl acetate than NiO. The in-situ DRIFTS elucidated the reaction path of catalytic ozonation of toluene and indicated that the introduction of CTAB facilitated the complete oxidation of by-products into CO2 and H2O.

“…Nonionic surfactants are thought to be one of the greatest environmentally friendly between the other forms of surface active agents [5]. Charged surfactants comprising cationic, anionic, zwitterionic and amphoteric possess risky environmental effect [6]. Surfactants, in specifically, could be employed as antimicrobial operators owing to their molecular structure and ability to engage with biological films [7].…”

The biological activities of poly (ethylene glycols) (PEG) that esterified with lauric acid or myristic acid were enhanced by mixing with zinc oxide nanoparticles (ZnO-NPs) derived as of hazardous trash "Electric Arc Furnace Dust (EAFD)" which formed through steel fabrication using sodium hydroxide (NaOH). A diverse temperature was applied to characterize and examine the prepared polymeric surfactants those possess characteristics of surfactant and polymer together. The surface properties were measured and worked out. The hydrodynamic particle diameter normally maximized as the surfactant carbon numbers increased and at blending with ZnO-NPs as exhibited in the dynamic light scattering (DLS) statistics due to aggregation of molecules. The antimicrobial action against different microorganisms of all such designed structures was assessed and assigned. The results plain that, all such engineered nonionic polymeric surfactants possess good surface criteria and biological activity and blending them with ZnO-NPs to obtain polymeric surfactant nanocomposites for enhancing their biological activity against Gram-positive bacteria (Bacillus subtilis and Staph. aureus), Gram-negative bacteria (P. aeruginosa and E. coli), yeast (Candida albicans) and microalga (Chlorella Vulgaris).
