Sputtering-deposition of Ru nanoparticles onto Al2O3 modified with imidazolium ionic liquids: synthesis, characterisation and catalysis.
Well-distributed Ru nanoparticles (Ru-NPs) were produced over Al(2)O(3) supports modified with covalently anchored imidazolium ionic liquids (ILs) containing different anions and cation lateral alkyl chain lengths by simple sputtering from a Ru foil. These Ru-NPs were active catalysts for the hydrogenation of benzene. Furthermore, depending on the nature of the IL used to modify the support (hy...
متن کاملSynthesis and Thermal Characterization of Mono and Dicationic Imidazolium Pyridinium Based Ionic Liquids
A series of monocationic and dicationic ionic liquids, in which each ionic liquid is associated with dicyanamide anion, are synthesized. The molecular structures of these compounds were identified by 1H-NMR, FT-IR and CHN analysis. Thermal behaviors of these ionic liquids were also investigated by thermogravimetry (TGA). The results suggested that all new ionic liquids have reasonable thermal s...
متن کاملX‐ray Photoelectron Spectroscopy of Pyridinium‐Based Ionic Liquids: Comparison to Imidazolium‐ and Pyrrolidinium‐Based Analogues
We investigate eight 1-alkylpyridinium-based ionic liquids of the form [Cn Py][A] by using X-ray photoelectron spectroscopy (XPS). The electronic environment of each element of the ionic liquids is analyzed. In particular, a reliable fitting model is developed for the C 1s region that applies to each of the ionic liquids. This model allows the accurate charge correction of binding energies and ...
متن کاملPhoto-degradation of Imidazolium Ionic Liquids
Degradation of imidazolium ionic liquid, [bmim][TFSA] and iodide solution of [bmim][TFSA] by UV-laser irradiation has been studied through ground state absorption and transient absorption spectroscopy. We found that excited state [bmim] undergoes degradation efficiently. Introduction Room-temperature ionic liquids are receiving considerable attention because of their remarkable properties, such...
متن کاملDual-functionalised ionic liquids: synthesis and characterisation of imidazolium salts with a nitrile-functionalised anion.
A series of 'dual-functionalised' ionic liquids, comprising imidazolium cations with various functionalities and the nitrile functionalised anion [CH3CH(BF3)CH2CN]- have been prepared; some exhibit very low viscosities-a highly valuable property in many applications.
