Abstract Nanoplates of Cu2WSe4 (~50 nm) were synthesized via a hot-injection method by one-pot selenation of WCl6 and Cu(acac)2. This synthetic route provided another path towards deciphering the intrinsic electrochemical properties of Cu2MSe4 (M = Mo or W), where their nanoparticles were previously synthesized via a metathesis route. Cation-dependent cathodic events and surface activation anodic events were identified by cyclic voltammetry in acetonitrile.

The bis(octacyanophthalocyaninato)neodymium(III) was synthesized and its electrochemical behavior in N,N-dimethylformamide ( DMF ) was investigated by cyclic voltammetry (CV) and square wave voltammetry (SWV). Multiple redox reactions were observed on the cyclic voltammogram, although the voltammetric feature was complicated due to aggregation. With the aid of SWV, it was concluded that the redox potentials of the complex positively shifted by about 700 mV compared with potentials of the unsubstituted complex, which was ascribed to the strong electron-withdrawn effect of the substituted cyano group.

Seven novel ferrocene derivatives containing (methylamino)benzonitrile and N-methylnitroaniline groups (3a-3f and 4) have been synthesized by conventional methods and characterized by FT-IR, NMR and cyclic voltammetry. The electrochemical behavior of these compounds (3a-3f) has been studied by cyclic voltammetry measurements at a platinum electrode in acetonitrile/0.1 M TBAP. The ferrocenyl group in all compounds showed similar reversible one-electron redox process, suggesting that the ferrocene moieties are equivalent and that there are no interactions among them. The formal potential, , is shifted to the more positive potential, indicating that the (methylamino)benzonitrile and N-methylnitroaniline introduced to ferrocene moiety exercise an electron-withdrawing effect.

Graphene oxide (GO)-modified polypyrrole (PPy) coatings were obtained by electrochemical methods in the presence of the anionic surfactant, sodium dodecyl sulfate (SDS). The structure, morphology, and electrochemical properties of the coatings were assessed by Fourier transform infrared (FTIR) spectroscopy, Raman spectroscopy, scanning electron microscopy (SEM) and cyclic voltammetry at varying scan rates, respectively. The properties of the obtained coatings were analyzed with the GO and PPy loadings and electrodeposition mode. The hybrid coatings obtained galvanostatically showed a coarser appearance than those deposited by cyclic voltammetry CV mode and improved performance, respectively, which was further enhanced by GO and PPy loading. The capacitance enhancement can be attributed to the SDS surfactant that well dispersed the GO sheets, thus allowing the use of lower GO content for improved contribution, while the choice of suitable electrodeposition parameters is highly important for improving the applicability of GO-modified PPy coatings in energy storage applications.

Nanoparticles of Ag with different sizes and structures were obtained and studied. Two methods for reductions of Ag ions were employed, chemical reduction by sodium borohydride and ethylene glycol. Cuboctahedral and icosahedral structures were obtained. Molecular simulations were carried out in order to evaluate the reactivity of both structures. On the other hand, the electrochemical activity and antibacterial effect (E. coli) of the cuboctahedral and icosahedral structures were measured experimentally. The results obtained by molecular simulation, cyclic voltammetry, and antibacterial effect were compared and discussed in this work.
