“…A series of studies performed during the last decade has proved the replacement of conventional organic solvents by Ionic Liquids (ILs) or CO 2 to be very advantageous [ 5 , 126 , 127 , 128 , 129 , 130 , 131 ]. ILs have many attractive and unique properties such as negligible vapor pressure, high conductivity, thermal stability, broad liquid range, and good tunability by using cation-anion combinations [ 132 ].…”

“…However, most of the latest reviews on the models that describe µEs structure and behavior go back to the 1990s. Dealing with such a diverse span of applications is no surprise that the reviews that have come out over the last 20 years, like the synthesis of organic nanoparticles [ 4 ] or the use of Ionic Liquids (ILs) [ 5 ], deal with very specific application areas of µEs. On the other hand, in the last 10 years, there is a lack of papers dedicated to summarizing the knowledge we have gained on the microstructure of µEs and to critically compare the different models proposed to describe and formulate these systems.…”

Microemulsion Microstructure(s): A Tutorial Review

et al. 2020

View full text Add to dashboard Cite

Microemulsions are thermodynamically stable, transparent, isotropic single-phase mixtures of two immiscible liquids stabilized by surfactants (and possibly other compounds). The assortment of very different microstructures behind such a univocal macroscopic definition is presented together with the experimental approaches to their determination. This tutorial review includes a necessary overview of the microemulsion phase behavior including the effect of temperature and salinity and of the features of living polymerlike micelles and living networks. Once these key learning points have been acquired, the different theoretical models proposed to rationalize the microemulsion microstructures are reviewed. The focus is on the use of these models as a rationale for the formulation of microemulsions with suitable features. Finally, current achievements and challenges of the use of microemulsions are reviewed.

Temperature and Pressure Dependence of the Infrared Spectrum of 1-Ethyl-3-Methylimidazolium Trifluoromethanesulfonate Ionic Liquid

et al. 2020

The infrared absorption spectrum of 1-ethyl-3-methylimidazolium trifluoromethanesulfonate (EMI–TfO) was investigated at ambient pressure and variable temperatures between 120 and 330 K, or at room temperature and variable pressures up to 10 GPa. Upon cooling, the ionic liquid crystallizes; on the contrary, upon compression no evidence of crystallization can be obtained from the infrared spectra. Moreover, Density Functional Theory (DFT) calculations were applied to gain a better description of the ionic couple. The ωB97X-D functional, including not only the empirical dispersion corrections but also the presence of a polar solvent, gives a good agreement with the infrared spectrum and suggests that TfO resides above the plane of the imidazolium, with the shorter distance between the O atom of the anion and the C2 atom of the imidazolium ring equal to 2.23 Å.

“…[ 76 ] With a wide range of intermolecular interactions (strong and weak ionic, hydrogen bonding, van der Waals, dispersive, n–π, and π–π interactions), ILs exhibit outstanding solvation properties compared to conventional organic solvents. [ 77 ] ILs can be employed to improve the chemical stability of BP. With fluorine‐containing IL as the electrolyte, the synchronous electrochemical fluorination of BP was realized by the reaction of the BP with the electrolyzed fluorine ions in the electrochemical exfoliation process.…”

Over the past few decades, the design and development of advanced catalysts for efficient energy conversion technologies have undergone extensive study. Black phosphorus (BP) is considered to be one of the most promising catalysts, exhibiting remarkable performance and drawing significant attention, because of its extraordinary physicochemical properties: a unique layered structure, anisotropic structure, tunable direct bandgap, and ultrahigh charge mobility. In this review, the fundamentals of bulk BP, single-and few-layer phosphorene, and BP quantum dots are briefly introduced, along with their crystal structure, optical and electrical properties, stability, and synthetic methods. Furthermore, recent progress toward diverse BP-based materials for photo-and electrocatalysis for renewable energy is summarized, specifically focusing on water splitting, CO 2 conversion, and nitrogen fixation. Finally, the challenges ahead for these BP-based catalysts are also emphasized, alongside and perspectives on their further development as part of the this fast-flourishing renewable energy field.
