Ionic liquids in electrochemical sensors

Multi-walled carbon nanotubes (MWCNTs) and room temperature ionic liquids (RTILs) carbon paste Er(III) sensor based on a new derivative of dansyl chloride

“…The good solvating properties, high conductivity, non-volatility, low toxicity, large electrochemical window (i.e. the electrochemical potential range over which the electrolyte is neither reduced nor oxidized on electrodes) and good electrochemical stability, make ILs suitable for many applications [1,2].…”

Triethanolammonium salicylate — Protic alkanolammonium ionic liquid

“…[1][2][3] Ionic liquids have attracted much attention in various fields of science and technology (electrochemistry, catalysis and organic synthesis, electrochemical sensors, and other areas) due to their unique properties as suitable solvents for a broad scope of inorganic, organic and polymeric materials. Their features such as high polarity, chemical and thermal stability, as well as a wide interval of liquid state, [1][2][3][4][5][6] draw interest to them of the large scope of chemist. Also, in recent years, ILs have attracted attention due to the possibility of the design of a new compounds with unique properties, e.g., pharmacologically active ionic liquids by combining cations and anions with desired properties [7][8][9].…”

Enhanced Electrocatalysis of the Oxygen Reduction Reaction Using Cobalt and Iron Porphyrin/Ionic Liquid Systems

“…Some of their properties include a low melting point, low vapor pressure, incombustibility, ability to dissolve a large number of compounds, high polarity, high conductivity, and high electrochemical stability. These properties vary according to the nature of the anion and cation by which they are composed . The variety of possible combinations between cations and anions turns ILs into adjustable materials in terms of their properties, making them more attractive for different fields .…”

“…These properties vary according to the nature of the anion and cation by which they are composed . The variety of possible combinations between cations and anions turns ILs into adjustable materials in terms of their properties, making them more attractive for different fields . In general, ILs are a good option as binders in carbon paste electrodes (CPEs), since they increment the faradaic and capacitive currents compared to conventional binders, such as mineral oil or paraffin.…”

“…[2] The variety of possible combinations between cations and anions turns ILs into adjustable materials in terms of their properties, making them more attractive for different fields. [2] In general, ILs are a good option as binders in carbon paste electrodes (CPEs), [1] since they increment the faradaic and capacitive currents compared to conventional binders, such as mineral oil or paraffin. Specifically, the combination based on N-octylpyridinium hexafluorophosphate (OPyPF 6 ; Figure 1) has shown favorable results toward electrochemical reactions.…”
