Elimination voltammetry with linear scan (EVLS) represents the fast and simple improvement of linear-sweep or cyclic voltammetric results. Through the various elimination functions, EVLS offers a new tool not also for better understanding of complex electrochemical processes on the surface of working electrodes, but also for improving the sensitivity of electrochemical measurements. The paper i...

The electronic and electron transfer behaviour of two examples of a recently discovered class of triple-decker sandwich complex based on three phthalocyanine ligands linked by two chelated cadmium ions has been investigated by EPR spectroscopy and cyclic voltammetry, square wave voltammetry and linear sweep voltammetry experiments. The two compounds, and , differ in the location of the eight al...

In this paper, the effect of surface area of reaction layers in gas diffusion electrodes on oxygen reduction reaction was investigated. For this purpose, various amounts (0.1, 0.2, 0.3, 0.4, 0.5, 1, 1.5 and zero %wt of total loading of reaction layer) of single walled carbon nanotube (SWCNT) were inserted in the reaction layer. The performance of gas diffusion electrodes for oxygen reduction re...

An efficient multi-walled carbon nanotube/gold colloidal nanoparticle paste electrode (MWCNTs/ Au Nps PE) was prepared for detection of hydrazine in the presence of pyrogallol red as a mediator in the homogenous solution. The prepared MWCNTs/ Au Nps PE and multi-walled carbon nanotube paste electrode (MWCNTs PE) were characterized by Raman spectroscopy, scanning electron microscopy and cyclic v...

Substitution of ionic platinum is carried out in Co3O4 host synthesized by solution combustion strategy.

Electrochemical deposition from a 0.1 M sodium sulphate solution, containing Cu2+ (adjusted to pH 3 with hydrochloric acid) produced a well defined copper nanoparticle deposit on the surface of a boron doped diamond electrode. Changing conditions such as potential (-0.8, -1.0 and -1.2 V), time (5, 2 and 0.5 s) and concentration of Cu2+ (500, 250 and 100 microM) was found to give copper nanopart...

In this paper, electrodeposition and visible light photocurrent responses of Zn-doped Cu2O were reported.
