In this work, electrochemical methods such as Tafel polarization and electrochemical impedance spectroscopy (EIS) were used to study the inhibition efficiency of Nettle leaves hydroalcoholic extract as a green corrosion inhibitor of API 5L carbon steel in 0.5 M H2SO4 solution. The results showed that the inhibition efficiency was increased with increasing the concentration of the extract and th...

Cyclic voltammetric studies were carried out on the deposition of polyaniline on pure aluminum from oxalic acid solution with and without different anions (CO3, SO3, SO4, DBS) and contribution of these anions to lyaniline film formation was investigated. Corrosion behavior of polyaniline coated aluminum in oxalic acid solution with and without different anions (CO3, SO3, SO4, DBS) has been inve...

In this data article, we presented the electrochemical data of the working electrode made of Co3O4 semi-transparent film. Electrochemically stable, porous nature of Kirkendall-diffusion grown Co3O4 films were applied to generate hydrogen from the seawater splitting (Patel et al., 2017) [1]. The data presented in this article includes the photograph of prepared samples, polarization curves for w...

A solution processed method for fabricating transition metal sulfides on fluorine doped tin oxide (FTO) as efficient counter electrodes in iodine/iodide based solar cells has been demonstrated. Conversion efficiencies of 7.01% and 6.50% were obtained for nickel and cobalt sulfides, respectively, comparable to the conventional thermally platinised FTO electrodes (7.32%). A comparable charge tran...

The electrochemical and corrosion behaviour of Al-6061, Al-4.5%Cu and Al-7.5%Cu alloys were studied in 0.50 M KSCN solution at 25 C. Open-circuit potential, Tafel polarization and ICP-AES measurements were used to study the uniform corrosion process on the surfaces of the tested alloys. Cyclic polarization measurements were employed for pitting corrosion studies. Obtained results were compared ...

Polarization and electrochemical impedance spectroscopy of p-type 6H-SiC electrodes in an aqueous hydrofluoric acid solution is performed during the formation of porous SiC. The polarization of p-type SiC permits the identification of the flatband voltage, a Tafel-like region, and a limiting current which is attributed to the onset of the electropolishing regime. For some of the potential range...

For the first time, the hydrogen evolution reaction (HER) electrocatalytic performances of incompressible γ-Mo0.5W0.5C, prepared by high-pressure, high-temperature (HPHT) synthesis, were investigated in the electrolyte. The polarization curve of the γ-Mo0.5W0.5C cathode exhibits the current density of 50 mA·cm−2 at an overpotential value of 320 mV. The corresponding Tafel slope of the incompres...

The corrosion inhibition characteristics of the derivatives of biopolymer hydroxypropyl methylcellulose (HPMC), hydroxypropyl methylcellulose phthalate (HPMCP), and hydroxypropyl methylcellulose acetate succinate (HPMCAS) film are investigated. Based on electrochemical impedance spectroscopic measurements and potentiodynamic polarization, the corrosion inhibition performance of high speed steel...
