Taking the advantage of the stability and penetrability of polyelectrolyte films formed by layer-by-layer (LbL) deposition, noble metal particles of Pd and Pt were fabricated in a preformed polyeletrolyte multilayer film by galvanic deposition. The metal deposition occurred as metal particles and they were tested for their properties as electrocatalyst for oxygen reduction. Atomic force microsc...

Multilayer assemblies of two crown-type type heteropolyanions (HPA), [Cu20Cl(OH)24(H2O)12(P8W48O184)](25-) and Ni4(P8W48O148)(WO2)](28-), have been immobilized onto glassy carbon electrode surfaces via the layer-by-layer (LBL) technique employing polycathion-stabilized silver nanoparticles (AgNP) as the cationic layer within the resulting thin films characterized by electrochemical and physical...

INTRODUCTION Various optical measurement techniques have been developed for the characterization of surface states during electrochemical processes. Surface plasmon resonance (SPR) spectroscopy has been used in combination with electrochemistry to investigate the electronic structure of metal-electrolyte interfaces [1]. We reported the current efficiency of refractive index changes that occurre...

A supported manganese porphyrin-based oxidation catalyst was prepared by zirconium-phosphonate multilayer assembly with [5,15-bis(4-phenylphosphonic acid)porphyrinato] manganese(III) chloride (2) and zirconium(IV) ions on indium–tin oxide electrodes. This assembly technique provided good control over the catalyst loading, which was confirmed by UV–Vis spectroscopy and cyclic voltammetry. Relati...

Electrodeposited aluminum films and template-synthesized aluminum nanorods are examined as negative electrodes for lithium-ion batteries. The lithium-aluminum alloying reaction is observed electrochemically with cyclic voltammetry and galvanostatic cycling in lithium half-cells. The electrodeposition reaction is shown to have high faradaic efficiency, and electrodeposited aluminum films reach t...

The electropolymerization behaviors of an electroactive and luminescent compound TCPC as precursor are studied. The resultant electrochemical deposition (ED) films are characterized by cyclic voltammetry (CV), UV-vis, fluorescence spectra, scanning electron microscopy (SEM), and atomic force microscopy (AFM). Under the CV mode with potential range of -0.5 to 0.85 V vs Ag/Ag(+), the coupling rea...

Polyelectrolyte multilayers built via the layer-by-layer (LbL) method has been one of the most promising systems in the field of materials science. Layered structures can be constructed by the adsorption of various polyelectrolyte species onto the surface of a solid or liquid material by means of electrostatic interaction. The thickness of the adsorbed layers can be tuned precisely in the nanom...

In Electrochemical Mechanical Planarization process (ECMP), concentrated phosphoric acid is usually used as electrolyte. Role of sodium dodecyl sulfate (SDS) in anodic dissolution of Cu in concentrated phosphoric acid was studied by Cyclic Voltammetry (CV), inhibition efficiency (IE) calculation and in-situ observation of the Cu electrode surface at anodic overpotentials. It was found that pres...

An indium tin oxide glass electrode coated with poly(3,4-ethylenedioxythiophene), PEDOT, PEDOT-ITOE, was proposed as an electrode workable as both a reference electrode and a counter one, a reference/counter electrode, in an organic phase and applied to a thin-layer cell of a two-electrode system for voltammetry at the liquid | liquid interface. By oxidizing the PEDOT film by 50% and doping a s...

Nanostructured ultrathin films of pendant carbazole-modified polyelectrolytes were fabricated using the layer-by-layer deposition technique in order to correlate the importance of highly ordered structures and well-defined layer composition in electrochemical cross-linking and nanopatterning. Both UV-vis and surface plasmon resonance (SPR) spectroscopy studies indicated differences in the film ...
