Electrocatalytic water electrolysis is the most promising clean and efficient process for pure generation of hydrogen. However, oxidation reaction requires a large overpotential owing to its slow kinetics, causing lower efficiency hydrogen production high energy consumption. Herein, we report bimetallic NiCu interconnected porous nanostructures on copper foil ([email protected]) prepared by bub...

Cathodic corrosion is a process that etches metal electrodes under cathodic polarization. This process is presumed to occur through anionic metallic reaction intermediates, but the exact nature of these intermediates and the onset potential of their formation is unknown. Here we determine the onset potential of cathodic corrosion on platinum electrodes. Electrodes are characterized electrochemi...

One method of creating a brass coating is through electrodeposition, which most often completed in cyanide galvanic baths. Due to their toxicity, many investigations focused on the development more environmentally friendly alternatives. The purpose study was explore new generation non-aqueous cyanide-free baths based 1-ethyl-3-methylimidazolium acetate ionic liquids. involved formation copper, ...

Anodic aluminium oxide (AAO) templates for multi-walled carbon nanotube (MWCNT) growth were produced by anodization of aluminium followed by pulse-reverse electrodeposition of cobalt inside the AAO pores. Cobalt functioned as the catalyst for H2/C2H2 chemical vapour deposition (CVD) growth of fairly well graphitized MWCNTs initiating inside the majority of the AAO pores and quickly growing beyo...

The evolution of corrosion morphology and kinetics for magnesium (Mg) have been demonstrated to be influenced by cathodic activation, which implies that the rate of the cathodic partial reaction is enhanced as a result of anodic dissolution. This phenomenon was recently demonstrated to be moderated by the use of arsenic (As) alloying as a poison for the cathodic reaction, leading to significant...

The macroparticle content of titanium films deposited using a steered vacuum cathodic arc has been investigated. It has been found that the macroparticle number decreases with increasing steering magnetic field strength, and experimental results are found to be consistent with the model in which the number and mass of macroparticles arising from a cathode spot are proportional to the cathode sp...

Manganese coatings are excellent for the cathodic protection of steel against corrosion. Although manganese is more electrochemically active than widely used protective zinc, exceptional resistance in neutral and basic media determined by film insoluble corrosion products, which forms on surface greatly suppresses its further It known that electrodeposition process Mn from sulphate electrolytes...

The hardness and corrosion resistance of nickel (Ni) deposit on a substrate could be reached by controlling electrolyte temperature during deposition. In this research, the electrodeposition Ni at various temperatures electrolytes was performed. Electrodeposited films using an optical digital camera, X-ray diffraction (XRD), scanning electron microscope with energy-dispersive x-ray spectroscopy...

In this work, a new type of block co-polymer additive, PE9400, was investigated for electrodepositing an ultra-low Sn coating in methanesulfonic acid (MSA) electrolyte. A thin coating with a loading of 0.7 gm 2 tin was fabricatedwith excellent uniformity and coverage on wet temper rolling steel (WTRS), when PE9400was used as an additive in the plating bath. Electrochemical measurements, real el...
