Electrostatic interactions are characteristic of ionic liquids (ILs) and play a pivotal role in determining the formation of species when solutes are dissolved in them. The formation of new species/complexes has been investigated for certain ILs. However, such investigations have not yet focused on eutectic liquids, which are a promising class of ILs. These liquids (or liquid coordination complexes, LCCs) are rather new and are composed of cationic and anionic chloro complexes of metals. To date, these liquids have been employed as electrolytes to deposit metals and as solvents for catalysis. The present study deals with a liquid that is prepared by mixing a 1.2:1 mol ratio of AlCl and 1-butylpyrrolidine. An attempt has been made to understand the interactions of FeCl with the organic molecule using spectroscopy. It was found that dissolved Fe(II) species interact mainly with the IL anion and such interactions can lead to changes in the cation of the electrolyte. Furthermore, the viability of depositing thick magnetic films of Fe and Fe-Al has been explored.

“…Thus, the utilization efficiency of Pt is exceptionally high. In recent years, various binary Pt alloy catalysts (PtCo, 58) PtFe, 9) PtNi, 10) PtCu 11) ) synthesized by electrodeposition have been proposed. This technique provides facile particle size control and plating-bath management.…”

Identical-Location Scanning Electron Microscopy Observation of Surface Morphological Changes of Pt–Cu Nanoparticles

The surface morphological changes of electrodeposited Pt75 at% Cu (Pt75Cu) nanoparticles under potential cycling were investigated by identical-location scanning electron microscopy. The electrodeposited nanoparticles consisted of numerous nuclei (³3 nm in diameter) that agglomerated to form larger secondary particles (3050 nm). Upon immersion in sulfuric acid, Pt shells formed on the surfaces of the Pt75Cu nanoparticles due to the selective dissolution of Cu. Although around 40% of the Cu was dissolved from Pt75Cu, no noticeable surface morphological changes were observed. Thereafter, Pt75Cu was subjected to potential cycling between 0.05 and 1.0 V, whereupon surface smoothing of the nanoparticles due to the surface diffusion of Pt was observed. Conversely, when Pt75Cu was potential-cycled between 0.05 and 1.4 V, the particle diameters of the nanoparticles drastically decreased and the nuclei on the surface completely disappeared owing to Pt dissolution and re-deposition. The heat-treated nanoparticles developed numerous pores on their surfaces during immersion and the initial stage of potential cycling. However, their final morphologies were found to be similar to those of the non-heated sample. The formation of pores can be explained by the coarsening of nuclei by heat treatment.

“…Ionic liquids (ILs) are low temperature melting salts (below 100 o C) [2,3]. These have been widely used as alternative reaction media to conventional organic solvents [4][5][6] and in electrochemistry [7,8]. Evolved from the latter, di-, tri-and tetracationic organic salts have become ideal materials in solving several problems [9].…”

ABSTRACT. This report describes the synthesis of a tetracationic organic salt from 4,4'-bipyridine and 1-bromooctane using 1,3-dibromopropane as a spacer just in three simple steps. A careful monooctylation of one of the nitrogen atoms of 4,4'-bipyridine using 1-bromoocatane followed by the dimeriztion using 1,3-dibromopropane as a linker resulted a tetracationic organic salt of formula [C3H6(C8Bipyr)2]Br4. 1 H and 13 C NMR, and CHN elemental analysis as well as ultra high vacuum spectroscopic technique (XPS) were employed to confirm the synthesis and the purity of this compound. This compound has demonstrated molar conductivity of 4320 S cm 2 mol -1 unexpected from a salt with 1:4 cation to anion ratio. It is expected that this salt would have potential applications in materials such as for low-molecular-weight gelators and the preparation of solid films for organic electronic applications.
