“…Electrochemical techniques using Schiff bases ligands have been widely reported for the detection of organic and inorganic compounds in a number of different matrices at very low concentrations [15] . It is a symmetrical molecule and exhibits chiral properties.…”

“…Electrochemical techniques using Schiff base ligands have been widely reported for the detection of organic and inorganic compounds in a number of different matrices at very low concentrations. 15 In this present study, the modied electrode, MWCNT-BZE-[bmim]PF 6 -Naon-GCE was developed. The performance and most signicant factors inuencing the modied electrode for Ag(I) ion detection were optimized.…”

A novel Ni–Schiff base complex for motivating glucose electrooxidation in alkaline solutions

“…Additionally, carbon paste containing polystyrene functionalized by a pentadentate Ni( ii )–Schiff base complex was prepared and used for the electrooxidation reaction of methanol and its aliphatic analogs. 47 It revealed a good electrocatalytic activity towards methanol, ethanol and isopropanol. The Schiff base of the Ni complex, Ni II -( N , N ′-bis(2,3-dihydroxybenzylidene)-1,2-diaminobenzene)(Ni( ii )-2,3dhS) was prepared and used as a sensor for the determination of glucose and fructose in honey.…”

Electrocatalytic Oxidation of Methanol, Ethanol, and Glycerol on Ni(OH)2Nanoparticles Encapsulated with Poly[Ni(salen)] Film

“…1 Previous work has demonstrated that an uncycled pentadentated nickel(II)-shift base catalyst graphed on polystyrene presents quite reasonable activity for the oxidation of alcohols, such as methanol and ethanol, but the effect of previous electrode cyclings and the possibility of forming Ni-based nanocatalyst centers were not considered. 29 In this work, the electrocatalytic activity of electrodes modified with Ni(II)-salen polymer film in alkaline medium was investigated for the electro-oxidation of Cn alcohols (Cn = methanol, ethanol, and glycerol). The prepared catalyst was characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), ultraviolet−visible spectroscopy (UV−vis), and cyclic voltammetry (CV).…”

“…In this context, Schiff base transition metal complexes have been explored as prospective materials for energy storage devices, − catalytic systems, ,, and electrochemical sensors. , It has been observed that these materials exhibit high control and homogeneity of the layer when electropolymerized on the electrode surface, high conductivity, reversible electrochemical oxidation, high thermal stability, and, more recently, a way of obtaining homogeneous and low-size nanoparticles. , In particular, the N , N ′-bis­(salicylidene)­ethylenediaminonickel­(II) complex, [Ni­( salen )], has been found to be active for the electro-oxidation of alcohols, such as methanol, ethanol, and glycerol in alkaline medium. , The vast application of nickel-based electrocatalysts is because they present electrocatalytic activity, antipoisoning capabilities, and long-term stability in alkaline solutions, as well as they are competitively priced materials, making them attractive candidates for numerous applications .
