Due to their interesting features including negligible volatility, ease of designing in the construction, good chemical, and thermal stabilities, and excellent ionic conductivity, ionic liquids (ILs) have attracted a lot of attention to themselves in recent years. They are constructed from asymmetric anions and cations and are found in a liquid state lower than 100 • C. Their unique features introduce them as candidates for the application in the structure of different types of electrochemical biosensors, in which they could act as electrolytes, or could be used

“…However, high concentrations of PA are highly corrosive, and this initiated major problems that included damaging the mechanical structure of the cells. Additionally, at higher temperatures, hydration of phosphoric acid and formation of pyrophosphoric acid oligomers reduced the conductivity of PA/PBI [102][103][104]. Therefore, several approaches were proposed, and recently, ILs were presented as a promising solution.…”

Increasing world energy demand and the rapid depletion of fossil fuels has initiated explorations for sustainable and green energy sources. High-temperature polymer electrolyte membrane fuel cells (HT-PEMFCs) are viewed as promising materials in fuel cell technology due to several advantages, namely improved kinetic of both electrodes, higher tolerance for carbon monoxide (CO) and low crossover and wastage. Recent technology developments showed phosphoric acid-doped polybenzimidazole (PA-PBI) membranes most suitable for the production of polymer electrolyte membrane fuel cells (PEMFCs). However, drawbacks caused by leaching and condensation on the phosphate groups hindered the application of the PA-PBI membranes. By phosphate anion adsorption on Pt catalyst layers, a higher volume of liquid phosphoric acid on the electrolyte–electrode interface and within the electrodes inhibits or even stops gas movement and impedes electron reactions as the phosphoric acid level grows. Therefore, doping techniques have been extensively explored, and recently ionic liquids (ILs) were introduced as new doping materials to prepare the PA-PBI membranes. Hence, this paper provides a review on the use of ionic liquid material in PA-PBI membranes for HT-PEMFC applications. The effect of the ionic liquid preparation technique on PA-PBI membranes will be highlighted and discussed on the basis of its characterization and performance in HT-PEMFC applications.

“…The active surface area of the modified GCE was determined using 1 mM ferrocene, a standard redox couple in 0.1M KCl as the supporting electrolyte at room temperature, and Randles-Ševčik equation. For a reversible redox process, the peak current is expressed as ip = 2.69 ×10 5 n 3/2 ADapp 1/2 Coν 1/2 (5) where ip represents anodic peak current, n = 1 is number of electrons transferred, A is active surface area of electrode, Dapp = 0.16×10 -6 cm 2 s -1 is diffusion coefficient of ferrocene [29], ν is potential scan rate and Co is bulk concentration of ferrocene (1 mM). The active surface area of the modified electrode is determined as 0.54 cm 2 , which is about 7 times greater than the geometric area (0.0707 cm 2 ) of bare GCE.…”

In order to raise possible ways of MoO3 synthesis and improve its existing applications, MoO3 nanomaterial was successfully synthesized through the solvo-hydrothermal route by utilizing a mixture of ionic liquid (1-butyl-3-methylimidazolium bromide) as a solvent, and water as co-solvent in 1:1 ratio. The morphology and structural parameters of IL-assisted MoO3 product were examined by X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FT-IR), and scanning electron microscopy (SEM). Additionally, the surface wettability and particle size distribution were inspected using the contact angle and dynamic light scattering (DLS) analysis. Glassy carbon electrode (GCE) surface was then modified by IL-assisted MoO3. The formed IL-MoO3/GCE was employed as an electrochemical sensor for determination of 4-nitrophenol (4-NP), which is very toxic and important pollutant. The redox behavior of 4-NP at the surface of IL-MoO3/GCE was investigated by cyclic voltammetry (CV) and differential pulse voltammetry (DPV) techniques. Limits of detection (LOD) and limits of quantification (LOQ) determined from CV were found to be 6.76 and 22.5 mM, while from DPV recordings, 5.41 and 18.0 mM are found. The obtained results clearly reveal possible application of MoO3 for selective and sensitive sensing of 4-NP. The decorated electrode was successfully employed for determination of 4-NP in the river water real samples.
