The electrochemical behaviour of ferrocene (Fc) is investigated in six different deep eutectic solvents (DESs) formed by means of hydrogen bonding between selected ammonium and phosphonium salts with glycerol and ethylene glycol. Combinations of cyclic voltammetry and chronoamperometry are employed to characterise the DESs. The reductive and oxidative potential limits are reported versus the Fc...

The kinetics of a thin layer Pd H(D) electrode at the coexistence of a and b phases in cyclic voltammetry are studied and the effects of various parameters are discussed. It is found that the voltammogram of the alb phase transition is trigonal in shape which differs significantly from those for diffusion and adsorption. The kinetic characteristics of the a+b mixed region are controlled by the ...

Excitation of the weak electron donor decamethylosmocene on illumination with white light produces an excited-state species capable of reducing organically solubilized protons under biphasic conditions. Insight into the mechanism and kinetics of light-driven biphasic hydrogen evolution are obtained by analysis with gas chromatography, cyclic voltammetry, and UV/Vis and (1)H NMR spectroscopy. Fo...

Zinc oxide nanocomposite was prepared by sol gel method. Synthesized nanoparticle was characterized by X-ray diffraction and FT-IR spectroscopy. According to XRD analysis the crystallite size was found to be 30nm (approx) for ZnO. The formation of ZnO is confirmed by FT-IR. ZnO is used for the preparation of HRP/ ZnO/PVA/Au electrode. ZnO nanocomposite is mixed with PVA Solution and a thin laye...

Cobalt(II) and manganese(III) phthalocyanines bearing peripherally and non-peripherally tetra substituted {(2E)-3-[4-(dimethylamino)phenyl]prop-2-enoyl}phenoxy groups were synthesized by cyclotetramerization of the phthalonitrile derivatives and their electrochemical properties were examined using CV and SWV techniques for the first time. The novel compounds were characterized by using IR, (1)H...

The reaction of [Ni(L)]Cl(2)·2H(2)O (L = 3,14-dimethyl-2,6,13,17-tetraazatricyclo [14,4,0(1.18),0(7.12)]docosane) with trans-1,2-cyclopentanedicarboxylic acid (H(2)-cpdc) yields a 1D hydrogen-bonded infinite chain with formula [Ni(L)(H-cpdc(-))(2)] (1). This complex has been characterized by X-ray crystallography, spectroscopy and cyclic voltammetry. The crystal structure of 1 exhibits a distor...
