Electrochemical post-treatment of ultrathin carbon layer coated cobalt nanoparticles generates a novel electrocatalyst, affording a small overpotential of 333 mV at a current density of 10 mA cm(-2) and a small Tafel slope of ∼58 mV per decade.

Electrocatalytic behavior of commercially available Fe-17Cr-14Ni alloy as a cathodic material for the evolution hydrogen in alkaline solutions has been characterized by means microstructural and electrochemical techniques. The microstructure alloys was examined scanning electron microscopy (SEM) X-ray diffraction (XRD) measurements. materials studied through potentiodynamic polarization techniq...

In this investigation, potentiodynamic polarization experiments were conducted on UNS S31603 and N08367 in a modified green death solution, which simulates the environment of desulfurization device (scrubber), using temperature as variable. A Tafel analysis showed that corrosion current density at highest (90 °C) was approximately 4.5 times higher than N83067. surface scanning electron microsco...

The paper presents data on the study of electrocatalytic properties Ni–Mo thin films in neutral and alkaline media, obtained as a result electrochemical synthesis. Comparative characteristics deposited Ni-Mo various substrates different compositions with catalytic activity Ni, Pt St-3 were determined by method recording linear polarization curves determining slope Tafel curves. highest was exhi...

In this paper, the role of nickel-20 chromium and TiO2 nanoparticles additions for enhancement corrosion resistance microhardness organic zinc-rich coatings were investigated. Three coating samples prepared by new in different amounts that experimentally predicted. Particle sizes micrographs examined scanning electron microscope (SEM) chemical composition was analyzed energy dispersive spectros...

Outstanding issues regarding the redox switching characteristics and the oxygen evolution reaction (OER) electrocatalytic behaviour of multicycled iron oxyhydroxide films in aqueous alkaline solution have been examined. Charge percolation through the hydrous layer has been quantified, using cyclic voltammetry, in terms of a charge transport diffusion coefficient D(CT) which admits a value of ca...
