Abstract:Copper metal and copper(I) oxide (cuprite, cuprous oxide) nanoparticles (Cu-NPs and Cu 2 O-NPs) were prepared from different readily available copper salts by means of microwave irradiation in propylene carbonate (PC) or in the ionic liquid (IL) 1-butyl-3-methylimidazolium tetrafluoroborate ([BMIm] [BF 4 ]) without addition of extra reducing agents. The nanostructures were studied by high-angle annular dark fieldscanning transmission electron microscopy, TEM, SEM, and powder XRD. Star-shaped agglomerated Cu-NPs with about 45 nm diameter were formed from Cu(BF 4 ) 2 in PC. Cu-NPs with

“…141,186 From these pioneering works, interesting examples of this strategy can be found in the literature, which report the use of nanoparticles (NPs) with or without solid supports. [187][188][189][190][191][192] Supported NPs offer several advantages over the use of unsupported NPs, such as better control of metal dispersion and particle morphology, inhibition of particle aggregation, and generally better reuse of the catalytic system. Given these attributes, different supported and recyclable CuNPs were employed in CuAAC reactions, among the supports employed are alumina, 193 aluminum oxyhydroxide, 194 montmorillonite, 195 MOF, [196][197][198] Cellulose, 199 SBA-15, 200 Zeolite, 201 and more recently graphene oxide.…”

The applications of the 1H-1,2,3-triazole derivatives are particularly attractive and have received prominent attention in scientific research. The characteristics of these heterocycles motivated the development of different strategies for their preparation and molecular diversification. Most of the synthetic procedures available in the literature are based on catalysis with copper salts. Therefore, this review has as complementary central focus and updates the information about the properties and the main methods for the preparation of 1H-1,2,3-triazole derivatives, with emphasis on methods involving 1,3-dipolar cycloaddition between organic azides and terminal alkynes catalyzed by copper.

“…ILs have gained significant attention as sustainable alternatives to traditional volatile organic compounds (VOCs) because they are non-flammable and have negligible vapor pressures, mitigating their emissions into the atmosphere and ultimately decreasing their environmental impact . ILs are widely employed in a variety of synthetic chemistries, − including as solvents for inorganic nanoparticle syntheses. − ILs are also known to exhibit an extraordinary ability to extract metal ions for extraction and recovery processes. − However, the relatively high cost of ILs over traditional organic solvents greatly hinders their practical application in industrial processes . It is therefore essential to reuse or recycle ILs; techniques for IL recycling without degradation of IL quality have been a topic of considerable research.…”

Industrial applications of ionic liquids (ILs)solvents that can serve as green alternatives to volatile organic compoundsare often hampered by their high cost. Solvent recycling provides a feasible pathway to recover IL solvents to reduce lifecycle costs. Herein, we demonstrate a continuous microfluidic process to purify metal-ion-loaded IL solvents, wherein Fe(III) ions are extracted from a prototypical IL, 1-butyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide (BMIM-NTf2), to deionized (DI) water with subsequent membrane separation of the IL and aqueous phases. Inline analytical tools, design of experiment statistical optimization, and a self-optimizing, modified Nelder-Mead simplex algorithm facilitate locating the best parametric operating conditions to optimize both ion extraction and physical phase separation. This process was then adapted to a more challenging purification application: recovery of the IL trihexyl(tetradecyl)phosphonium bis(2,4,4-trimethyl-pentyl)phosphinate (Cyphos 104) from the rare-earth metal Nd(III). This application demonstrated that optimized conditions obtained from a single stage could be applied across a multistage process. Together, these results demonstrate that statistical and inline optimization tools can be used to identify working parameters for different flow systems with a variety of governing fluid properties, for example, viscosity and interfacial tension.
