“…There are reports on the synthesis of inorganic compounds like platinum, palladium, and rhodium [73], nanoiron [74], nickel oxide [75], and ceramic particles [57] that employ glycan-based surfactant nanoreactors. It has been less than forty years since the pioneering work of Boutonnet et al in 1982, where they reported the preparation of metallic nanoparticles in an emulsion system [76].…”

“…Hada et al reported the preparation of nickel oxide nanoparticles (NPs) using a single microemulsion system by hydrolysis of nickel chloride hexahydrate [75]. The mixed reverse microemulsion was prepared by stirring cyclohexane, isopropanol, aqueous solution of nickel salt with a mixture of Tween 80 with sodium dioctyl sulfosuccinate (AOT), and an anionic surfactant at room temperature.…”

The nanoreactor concept and its application as a modality to carry out chemical reactions in confined and compartmentalized structures continues to receive increasing attention. Micelle-based nanoreactors derived from various classes of surfactant demonstrate outstanding potential for chemical synthesis. Polysaccharide (glycan-based) surfactants are an emerging class of biodegradable, non-toxic, and sustainable alternatives over conventional surfactant systems. The unique structure of glycan-based surfactants and their micellar structures provide a nanoenvironment that differs from that of the bulk solution, and supported by chemical reactions with uniquely different reaction rates and mechanisms. In this review, the aggregation of glycan-based surfactants to afford micelles and their utility for the synthesis of selected classes of reactions by the nanoreactor technique is discussed. Glycan-based surfactants are ecofriendly and promising surfactants over conventional synthetic analogues. This contribution aims to highlight recent developments in the field of glycan-based surfactants that are relevant to nanoreactors, along with future opportunities for research. In turn, coverage of research for glycan-based surfactants in nanoreactor assemblies with tailored volume and functionality is anticipated to motivate advanced research for the synthesis of diverse chemical species.

“…The NiO-NPs were synthesized by the microemulsion method due to the fact that it has been proven to present the favourable features of large interfacial areas, low interfacial tension, and thermodynamical stability. 39 The appropriate amounts of methylcyclohexane, water, surfactant AEO9, and octanol were mixed in continuous oil phase and stirred vigorously at 1500 rpm at 30 • C to obtain the microemulsion system; 0.1-mol/L nickel nitrate aqueous solution was added to the stirring system until fully dissolved to obtain the microemulsion solution comprising nickel ions. Lithium borohydride was then added to the system under vigorous stirring and low-temperature conditions.…”

Summary Nickel oxide nanoparticles were synthesized by microemulsion method and characterized by powder X‐ray diffraction, dynamic light scattering, and scanning electron microscopy. Thermal analyses were performed to identify the influence of nickel oxide nanoparticles on the in situ combustion of Liaohe heavy oil. Low‐temperature oxidation and coking process were investigated by analysing the effluent gases and the fractions of saturates, aromatics, resins, and asphaltenes. Combustion tube tests were also conducted to evaluate the catalytic performance of nickel oxide nanoparticles. Compared with the runs without catalysts, the effective activation energies were reduced by 4.22%, 20.57%, and 35.75% in terms of low‐temperature oxidation, pyrolysis, and high‐temperature oxidation, respectively. The reduction in O2 fraction and the increase in CO2 and O2 uptake were also confirmed. The overall trend presented the increase of saturates and aromatics fraction and the decline of resins and asphaltenes fraction while temperature was increased during low‐temperature oxidation. Adding nickel oxide nanoparticles led to the reduction in the fuel deposit during pyrolysis. Compared with the base combustion tube runs, combustion time in catalytic experiment was shortened by 12.1%, combustion front movement was accelerated by 9.1%, oil recovery was enhanced by 4.0%, and oil viscosity was reduced by 61.2%.

“…Micellar (microemulsion) synthesis is widely used for the production of monodisperse NPs of predetermined size and shape . Numerous procedures have been developed for manufacturing NPs in the form of both ultradisperse powders and stable organosols. ,− In particular, organosols on the basis of NPs of metals and sodium bis(2-ethylhexyl) sulfosuccinate (AOT) are promising systems for developing new recipes of e-inks and new procedures of analysis. However, despite the extensive studies, many problems, for example, the origin of the surface charge of NPs, influence of the initial volume of polar cavity on the sizes of grown NPs, , micelle structure containing NPs, − and many others, call for further research.…”

Photon correlation spectroscopy, nonaqueous electrophoresis, and transmission electron microscopy were used to study the structure of silver nanoparticles (NPs) in n-decane, as a dependence of the concentration of sodium bis(2-ethylhexyl) sulfosuccinate (AOT) and temperature. If the concentration of AOT is lower than the critical micelle concentration (CMC), a silver NP is covered with a monolayer of AOT and reveals no electrophoretic mobility. At average concentrations (from CMC to 0.1 M) the hydrodynamic diameter of a NP does not change, but the ζ-potential increases from 0 to 110 mV. When the concentration of AOT increases from 0.1 to 1 M, ζ potential drops to 13 mV, and the hydrodynamic diameter increases to 90 nm. An increase in temperature to 70 °C leads to a reversible decrease in diameter to 40 nm. The hypothesis of clustering (polylayer adsorption) of "empty" micelles on silver NPs is proposed for the qualitative interpretation of the experimental data.
