In this study, the gold nanoparticles (AuNPs) were synthesized via redox reaction, by using ethylene diamine tetra-acetic acid (EDTA) as a protecting and reducing agent, with tetrachloroauric acid (HAuCl4) as precursor and seed solution. The ultraviolet-visible spectroscopy (UV-Vis) method was utilized to investigated the reaction conditions (the EDTA:HAuCl4 ratio, the amount of seed solution and stirring solution time) at room temperature. The synthesized AuNPs were deposited on the surface of fluorine doped tin oxide (FTO) by electrophoresis deposition.

The rGO/CueCu2O deposited on the electrode surface was confirmed by scanning electron microscopy, transmission electron microscopy, X-ray diffraction, confocal microscopy, and electrochemical characterization. The analytical performance of the proposed rGO/CueCu2O-modified electrode was also compared with the CuO/rGO-modified electrode using commercial CuO nanoparticles.

A simple approach to constructing a double-layer voltammetric sensor is described. The poly(malachite green) (PMG) and multiwalled carbon nanotubes (MWCNTs) were coimmobilized at the surface of the glassy carbon electrode (GCE) for fabrication of PMG/MWCNT/GCE. The modified electrode was characterized by cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS), differential pulse voltammetry (DPV), and chronoamperometric techniques.

The kinetics of the iron electrodeposition reaction from a plating bath containing trivalent iron ions is investigated in the present work. The electrochemical reaction is stated to proceed via the formation of relatively stable intermediates: Fe(II) ions. Only a part of the total amount of Fe(II) ions formed at the first stage of Fe(III) discharge is reduced further, producing metal iron. The effect of polyhexamethyleneguanidine hydrochloride (with an average molecular weight of 1000) on the iron deposition is ascertained.

Cyclic voltammetry (CV) was performed on tamoxifen (tam) using different electrodes and in various acidic electrolytes containing 10% v v−1 methanol (MeOH). Tam oxidation was found to be most favorable using 0.1 mol L−1 H2SO4. To investigate the mechanism, we performed chronoamperometry, CV at different scan rates, differential pulse anodic voltammetry (DPAV), and electrochemical impedance spectroscopy on tam-covered glassy carbon electrodes (GCEs). The electrode area, diffusion coefficient, and surface concentration (Γ) of tam were calculated to be 0.062 cm2, 3.65 × 10−6 cm2 s−1 , and 3.

In this paper, we report a simple, low-cost, and environmentally friendly electrochemical method to obtain a novel copolymer consisting of 1-pyrenyl-2,5-di(2-thienyl)pyrrole and pyrrole on a pencil graphite electrode (PGE). Poly(1-pyrenyl)-2,5-di(2-thienyl)pyrrole-co-pyrrole) that is P(PyrPy-co-Py) film was prepared by one-step potentiostatic codeposition in an ethanol solution containing PyrPy and Py monomers for supercapacitor applications. The electrodeposition of homopolymer and copolymer modified electrodes was carried out on the surface of the PGE via chronocoulometry.

Herein, titanium (Ti3+) self-doped strontium titanate (SrTiO3), so-called blue SrTiO3, with a bandgap of 2.6 eV and favorable photocatalytic characteristics was fabricated through a facile and effective method. For electrochemical investigations, the electrophoretic deposition was applied to produce SrTiO3 thin films on (fluorine-doped tin oxide) FTO conductive substrates. The electrophoretic voltage of 20V and a process duration of 10 min were optimized to reach transparent and uniform coatings on FTO. The blue SrTiO3 reveals lower resistance (charge transfer resistance of 6.
