Cost-effective, efficient and stable electrocatalyst for water splitting in the acidic electrolyte medium has been developed. The could be a support high purity hydrogen production via splitting. Accordingly, we have prepared defect-rich titania nanostructure electrochemical anodization cathodization routes using titanium plate, which showed highly effective durable of evolution reaction (HER) ...

The influence of electrode surface structure on electrochemical reaction rates and mechanisms is a major theme in electrochemical research, especially as electrodes with inherent structural heterogeneities are used ubiquitously. Yet, probing local electrochemistry and surface structure at complex surfaces is challenging. In this paper, high spatial resolution scanning electrochemical cell micro...

In this study, an  organic compound  inhibitor, namely N-benzyl-N-(4-chlorophenyl)-1H-tetrazole-5-amine (NBTA), was synthesized and the role of this inhibitor for corrosion protection of stainless steel (SS) exposed to 0.5 M H2SO4 was investigated using electrochemical, and quantum analysis. By taking advantage of potentiodynamic polarization, the inhibitory action of NBTA was found t...

This paper suggested a de-noising algorithm used in grayscale images. As long as the noisy image does not give desired view of its features, is required. The based on block matching and wavelet transformation. Euclidean distance for blocks similarity exploited, which demonstrate more accurate finding similar depending soft thresholding. Regarding transform, combine hard thresholding performed H...

In this study, a new mild steel surface pretreatment solution is introduced based on phosphoric acid containing a benzimidazole derivative as inhibitor. In this way, three different benzimidazole derivatives namely benzimidazole BI, 2-methyl benzimidazole 2MBI and 2-aminobenzimidazole 2ABI were studied in the 1M H3PO4 using DC and AC electrochemical techniques. Results revealed the better corro...

12-molybdophosphoric acid (pmo12) was encaged into hmor zeolite by “ship in a bottle”method in aqueous phase which is strongly retained and not easily leached from the host channels.the solid was characterized by xrd prior to using it for the electrode preparation. this compoundwas incorporated with a carbon paste electrode for cyclic voltammetric measurements. pmo12immobilized on the support u...

this paper focused on the characterization of electrochemical behavior of a martensitic stainless steel inthe acidic solutions. for this purpose, electrochemical parameters were derived from potentiodynamicpolarization, mott schottky analysis and electrochemical impedance spectroscopy (eis) techniques.the potentiodynamic polarization results showed that corrosion current density of aisi 420 sta...

The electrochemical reduction of aqueous solutions of sulfite under acidic conditions on copper electrodes is reported, and a mechanism is proposed. Cyclic voltammetry at a copper disk suggests the operation of two reduction processes, the dominant process depending on solution pH. At very low pH (0-2), sulfur dioxide is reduced in a two-electron, two-proton reaction, but at higher pH (2-5), bi...

The effect of pH and electrochemical potential on copper uptake, xanthate adsorption and the hydrophobicity of sphalerite were studied from flotation practice point of view using electrochemical and micro-flotation techniques. Voltammetric studies conducted using the combination of carbon matrix composite (CMC) electrode and surface conduction (SC) electrode show that the kinetics of activation...
