In this research, the reactive absorption of carbon dioxide in an aqueous solution of NH3, H2O, and NaOH has experimentally been investigated. The experiments were carried out in an absorption pilot plant in different operational conditions. The composition and temperature of both gas and liquid phases were obtained during the column height. The concentration of molecular ...

Li metal negative electrode is expected for the next-generation Li battery electrode material, and the control of morphological variation of the Li metal electrode surface is very important issue. In-situ observation of the Li dendrite growth in an ionic liquid by an optical microscope was done in order to discuss the relationship between the Li dendrite growth and the Li ionic mass transfer ra...

By using ionic liquid 1-hexylpyridinium hexafluorophosphate (HPPF6) based carbon ionic liquid electrode (CILE) as the substrate electrode, a CoMoO4 nanorods and myoglobin (Mb) composite was casted on the surface of CILE with chitosan (CTS) as the film forming material to obtain the modified electrode (CTS/ CoMoO4-Mb/CILE). Spectroscopic results indicated that Mb retained its native structures w...

Carbon nanotube (CNT) gel, which is composed of a mixture of single-wall CNT, an ionic liquid, and a thermostable D-proline dehydrogenase (D-Pro DH) immobilized electrode was utilized for the determination of D-amino acids (DAAs) in food samples. When a critical comparison with CNT, Ketjen Black (KB), and carbon powder (CP) was also carried out, the CNT/D-Pro DH immobilized electrode showed the...

A simple and high sensitive electrochemical method was developed for determination of phenylephrine (PHE) in the presence of acetaminophen (AC) at the carbon-ceramic electrode modified by multi-walled carbon nanotubes/ionic liquid nanocomposite (MWCNTs/IL/CCE). Cyclic voltammetry (CV) and differential pulse voltammetry (DPV) and chronoamperometry methods were used for electrochemical studie...

The electrochemical sensing properties of graphene-based and carbon nanotube (CNT)-based electrodes towards ascorbic acid, dopamine, uric acid, and glucose are systematically compared. Nano-sized Pd catalyst particles are uniformly dispersed on both carbon supports using a supercritical fluid deposition technique to increase the sensing performance. The CNT/Pd electrode shows higher detection c...

A composite of graphene and carbon nanotubes has been synthesized and characterized for application as supercapacitor electrodes. By coating the nanostructured active material of Co(OH)2 onto one electrode, the asymmetric supercapacitor has exhibited a high specific capacitance of 310 F g-1, energy density of 172 Wh kg-1 and maximum power density of 198 kW kg-1 in ionic liquid electrolyte EMI-T...

A multi-walled nanotube (MWNT) ionic liquid was prepared by the immobilization of 1-butylimidazole bromide onto an epoxy group on a poly(glycidyl methacrylate)-grafted MWNT, which was synthesized by radiation-induced graft polymerization of glycidyl methacrylate onto MWNT in an aqueous solution. Subsequently, a MWNT ionic liquid electrode was fabricated by hand-casting MWNT ionic liquid, tyrosi...
