“…27 Moreover, the mean value of ks was obtained as 3.48 ± 0.06 s -1 . This is higher than those reported elsewhere in the literature 28,29 for the redox process of nickel species generated from nickel bulk metal. This result indicates that the nanoporous structure represents a higher electron-transfer rate in the redox process of nickel species in an alkaline solution compared to the microstructures represented in Refs.…”

Experimental Reagents and chemicalsAll other chemicals used in this work (otherwise those stated) were of analytical grade from Merck, and were used without further purification. Carbon micro-particles (graphite fine powder) with a particle size of less than 50 μm were obtained from Merck. Nafion solution was purchased from Sigma. All of the solutions were prepared by redistilled water. Acyclovir 2012 © The Japan Society for Analytical Chemistry † To whom correspondence should be addressed. Nickel microspheres were synthesized via a water-in-oil reverse nanoemulsion system using nickel nitrate as the nickel precursor and hydrazine hydrate as the reducing agent. The nanoemulsion was a triton X-100/cyclohexane/water ternary system. The surface morphology of the nickel microspheres was studied by scanning electron microscopy, which indicated that the microspheres had a nanoporous structure. The electrochemical behavior of the nanoporous nickel microspheres were studied in alkaline solution and were then employed to fabricate a modified carbon paste electrode in order to investigate the electrocatalytic oxidation of the drug acyclovir. The oxidation process involved, and its kinetics were investigated using cyclic voltammetry and chronoamperometry. The rate constant of the catalytic oxidation of acyclovir and the electron-transfer coefficient are reported. A sensitive, simple and time-saving amperometric procedure was developed for the analysis of acyclovir. The proposed amperometric method was also applied to determine acyclovir in tablets and topical cream.

“…14,15 However, the limitations of this method are that the mobile phase (eluent) must be alkaline and the electrode surface must be cleaned between the measurements. Some methods that employ a glassy carbon electrode (GC) have been reported, although sugar is usually undetectable with a GC; therefore, the GC is modified with Ni, 16,17 Co, 18 and Cu 19 for the detection of sugar using the electrocatalytic activity of a specific metal.…”

“…Organic-inorganic composite have attracted considerable attention as they can combine the advantages of both components and may offer special through reinforcing or modifying each other [30]. Electrodeposition is an effective way to make composite films with a large variety of tunable parameters and so has the advantage of convenient film control.…”

In this study we investigated the electrocatalytic oxidation of saccharose on conductive polymer-Nickel oxide modified graphite electrodes based on the ability of anionic surfactants to form micelles in aqueous media. This NiO modified electrode showed higher electrocatalytic activity than Ni rode electrode in electrocatalytic oxidation of saccharose. The anodic peak currents show linear dependency with the square root of scan rate. This behavior is the characteristic of a diffusion controlled process. Under the CA regime the reaction followed a Cottrellian behavior and the diffusion coefficient of saccharose was found in agreement with the values obtained from CV measurements.
