The utility of ionic liquids can primarily be traced to the pioneering work by Osteryoung et al. [3] on N-butylpyridinium-containing, and by Wilkes and Hussey [4—6] on l-ethyl-3-methylimidazoHum-containing ionic Hquids for electrochemical studies. These studies have strongly influenced the choice of ionic Hquids for subsequent research [7]. The vast majority of work pubHshed to date on room-temperature ionic Hquids relates to N-butylpyridinium and l-ethyl-3-methyHmidazoHum [EMIM] tetrachloroaluminate(III) systems. The large variety of available ion combi-...

So far the historical development of ionic liquids has mainly been driven by combining imidazolium, pyridinium, ammonium and phosphonium cations with different classes of anions. Chloroaluminate ionic liquids were the first more detailed studied ionic liquids. As early as 1948 they were synthesized by Hurley and Wier at the Rice Institute in Texas as bath solutions for electroplating aluminum [1], Later in the seventies and eighties, these systems were further developed by the groups of Osteryoung [2], Wilkes [3], Hussey [4] and Seddon [4c, 5], Due to their chemical nature, chloroaluminate ionic liquids must be classified as extremely hygroscopic and labile towards hydrolysis. 

In another publication Lipsztain and Osteryoung used imidazolium-based ionic liquids to study the behavior of Sb(III) under conditions where the unbuffered properties of a neutral ionic liquid played an important role [17]. 

Gale and Osteryoung [416] studied anodic and cathodic polarization of an aluminum electrode in the nominal 1 1 and 1 2 molar NaCl-AlCl3 molten electrolytes and found that these processes were Faradaic three-electron-step re-... 

Aluminum anodization in basic A1C13-MEIC melts was studied by Carlin and Osteryoung [462], and two different anodization processes were observed. The first step occurred in the catholic region, at a potential of -1.1 V, versus the aluminum electrode, and it was controlled by diffusion of chloride to the electrode surface. The authors found that the number of chlorides required to produce one A1C14 anion for each Al being anodized was 4. The second anodization which occurs on the anodic side of 0 V was not diffusion limited. It has not been possible to reduce the A1C14 anion in basic melts.

Ionic liquids (ILs), previously known as molten salts, were mainly used in electrochemistry studies due to their ionic nature. The most important step in the chemistry of the ILs occurred when Osteryoung described a mixture of 1-(1-butylpyridinium)-chloride and aluminium chloride which was liquid at room temperature30. Later on, Wilkes discovered other ionic liquids based on dialkylimidazolium salts that featured even more convenient physical and electrochemical properties than the butylpyridinium salts3i.

The electrochemistry of the polymeric and isomorphous cobalt(II) and nickel(II) methylsquarates was also studied by Iwuoha et al. In aqueous solutions, they found evidence that both the nickel(II) methylsquarate and its cobalt analog were dissociated without any reversible redox processes occurring for the metal ions. However, the cyclic and Osteryoung square wave voltammograms, obtained using a Pt electrode for solutions of these complexes in dimethylformamide and dimethylsulfoxide, contained signals attributable to both ligand-based and metal-based redox processes 142). 

Electrochemical data recorded under no steady-state conditions can also be used for studying electrocatalytic processes involving porous materials. In cases where the catalytic system can be approached by homogeneous electrocatalysis in solution phase, variation of cyclic voltammetric profiles with potential scan rate (Nicholson and Shain, 1964) and/or, for instance, square-wave voltammetric responses with square-wave frequency (O Dea et al., 1981 O Dea and Osteryoung, 1993 Lovric, 2002) can be used. This situation can, in principle, be taken for highly porous materials where substrate transport, as well as charge-balancing ion transport, is allowed. On first examination, the catalytic process can be approached in the same manner...
