Electrochemical Impedance Spectroscopy and its Applications
TL;DR: In this paper, the fundamental processes of diffusion and faradaic reaction at electrodes are discussed and a review of the applications of these processes can be found in a forthcoming volume in this series.
Journal ArticleDOI
Kinetics of hydrogen evolution on nickel electrodes
Andrzej Lasia,A. Rami +1 more
TL;DR: In this paper, the mechanism and kinetics of the hydrogen evolution reaction (HER) were studied in 1 M NaOH on polycrystalline nickel electrodes using potential step charging, open circuit potential decay and ac impedance techniques.
Journal ArticleDOI
Experimental study and modeling of impedance of the her on porous Ni electrodes
C. Hitz,Andrzej Lasia +1 more
TL;DR: In this paper, the electrochemical activity towards the hydrogen evolution reaction of pressed powder electrodes was studied in alkaline solutions after leaching out the more active element, and the electrodes displayed porous character, and electrochemical impedance spectroscopy was used to characterize surface porosity.
Journal ArticleDOI
Studies of the Hydrogen Evolution Reaction on Raney Nickel—Molybdenum Electrodes
L. Birry,Andrzej Lasia +1 more
TL;DR: In this article, the hydrogen evolution reaction was studied in 1 M KOH at 25 °C on two types of electrodes: pressed powders of Ni or NiMo with Al, heated at 700 °C; and Ni-Al-Mo powders deposited by vacuum plasma spraying.
Journal ArticleDOI
Electrodeposition of aluminium from ionic liquids: Part I—electrodeposition and surface morphology of aluminium from aluminium chloride (AlCl3)–1-ethyl-3-methylimidazolium chloride ([EMIm]Cl) ionic liquids
TL;DR: In this article, the electrodeposition and surface morphology of aluminium on tungsten (W) and aluminium (Al) electrodes from 2 −: 1 molar ratio AlCl 3 -[EMIm]Cl ionic liquids were investigated.
