For the first time the electropolymerization of 2,6-dihydroxynaphthalene (2,6-DHN) on a screen printed carbon electrode (SPCE) was investigated and evaluated for peroxynitrite (PON) detection. Cyclic voltammetry was used to electrodeposit the poly(2,6-DHN) on the carbon electrode surface. The surface morphology and structure of poly(2,6-DHN) film were investigated by SEM and FTIR analysis, and ...

Three xanthene dyes with different anchoring groups, eosin Y (EY), dicarboxy-eosin Y (CEY) and sulfonated eosin Y (SEY) were employed to electrodeposit ZnO/dye hybrid thin films to study the effect of anchoring groups on the electrochemical self-assembly (ESA) of hybrid thin films. The adsorption stabilities of the dyes in oxidized form were in the order, CEY >> EY > SEY, as evaluated by Langmu...

Electrochemical energy conversion is considered a promising method to alleviate the global crisis and environmental issues. By decreasing length scale atomic level, energy-related metal electrocatalysts can possess unique catalytic properties, which maximize their utilization. The electrodeposition technique has gained unprecedented attention for synthesis of atomic-level catalysts. In this rev...

The formation of low surface energy hybrid organic-inorganic micro-nanostructured zinc stearate electrodeposit transformed the anodic aluminum oxide (AAO) surface to superhydrophobic, having a water contact angle of 160 ̋. The corrosion current densities of the anodized and aluminum alloy surfaces are found to be 200 and 400 nA/cm2, respectively. In comparison, superhydrophobic anodic aluminum o...

Enhanced performance was observed for dye-sensitized solar cells (DSSCs) utilizing counter electrodes based on Pt electrodeposits compared to counter electrodes based on sputtered Pt. Scanning electron microscopy of Pt electrodeposits revealed that the use of an initial cathodic overpotential pulse followed by steady electrodeposition at a mild cathodic potential yielded ∼40nm particles, compar...

Nanoscale particles offer a variety of interesting properties, and there is growing interest in their assembly into higher ordered structures. We report that the pH-responsive aminopolysaccharide chitosan can mediate the electrodeposition of model nanoparticles. Chitosan is known to electrodeposit at the cathode surface in response to a high localized pH. To demonstrate that chitosan can mediat...

The influence of polyethyleneimine (PEI) on the electrochemical behavior of cyanide-free electrolytes with 5,5-dimethylhydantoin (DMH) as a complexing agent was investigated using cyclic voltammetry (CV), chronoamperometry, and cathodic polarization measurements. The gold electrodeposition displayed three-dimensional (3-D) progressive nucleation in both the absence and presence of PEI according...

Electrodeposition of multilayered semiconductors requires a bath design to electrodeposit the upper layer(s) without dissolving base below. We present herein reliable approach based on thermodynamics from viewpoint complexation with ligands. A CuO/Cu2O bilayer film was targeted as an example. searched thermodynamic database constants for ligands that could form complex Cu(II) but not Cu(I), and...

The trivalent Eu(III) ion exhibits unique red luminescence and plays an significant role in the display industry. Herein, amperometry electrodeposition method was employed to electrodeposit materials on porous Si terpyridine-functionalized surfaces. electrodeposited were fully characterized by scanning electron microscopy, X-ray diffraction crystallography, Fourier-transform infrared spectrosco...
