Abstract The effect of benzenethiol and its methyl, amino, and carboxylic ring substituted derivatives, benzylthiol and thioglycollic acid on the electrochemical and corrosion behavior of zinc in CH3COOH, H2SO4, and HCl solutions was studied using the galvanostatic technique. In CH3COOH, compounds which function by an adsorption mechanism were found to have inhibitive effects on the corrosion of zinc, while those functioning by surface chelation were ineffective. In H2SO4 and HCl, with the exception of o-methylbenzenethiol (H2SO4 and HCl) and benzylthiol (H2SO4), all investigated compounds were found to accelerate zinc dissolution. Adsorption of the inhibitors followed the Langmuir isotherm, and the mechanism of both the hydrogen evolution reaction and zinc dissolution were found to be the same in the uninhibited and inhibited states.

Porous Ni coatings were prepared by galvanostatic electrodeposition on the steel substrate from the Watts type bath at the deposition current densityjdep= -250 mA cm2at the temperature 40, 50 and 60°C. Investigations of hydrogen evolution reaction (HER) on the obtained Ni electrodes were carried out in 5 M KOH solution at room temperature. It was found that with the increase in the electrodeposition temperature of the coatings, the activity of the Ni electrocatalysts towards the HER decreased due to diminishing surface development of the Ni coatings.
