Hydrogen Evolution Reaction from EDTA Solutions
Materials Science Forum, 2002An attempt was made to investigate the mechanism and kinetics of hydrogen evolution reaction on zinc and platinum wire electrodes from solutions containing ethylene diamine tetraacetic acid (EDTA). EDTA is a tetra-basic acid whose dissociation covers a wide range of pH, with a betaine structure in solutions.

Hydrogen Evolution Reaction by Platinum Coating
Iranian Journal of Science and Technology, Transactions A: Science, 2021A thin layer of platinum coating (0.5 µgcm−2) on stainless steel surface was deposited by direct current (DC) and pulse current (PC) electrodeposition method for hydrogen evolution reaction (HER) application. Scanning electron microscopy, atomic force microscopy, and X-ray diffraction analysis were used to characterize the coatings.

Organocatalytic Hydrogen Evolution Reaction by Diazaphospholenes
Journal of the American Chemical SocietyThe electrochemical hydrogen evolution reaction (HER) is currently recognized as a prospective way to obtain clean energy. The electrocatalysts used currently are dominantly based on transition metals. In this work, we have demonstrated a diazaphospholene (N-heterocyclic phosphine (NHP))-type small molecular organocatalyst that can catalyze the HER ...

Electrocatalysts for hydrogen evolution reaction
International Journal of Hydrogen Energy, 2017Abstract In addition to the historical importance of water electrolysis, hydrogen evolution reaction (HER) is the heart of various energy storage and conversation systems in the future of renewable energy. The HER electrocatalysis can be well conducted by Pt with a low overpotential close to zero and a Tafel slope around 30 mV dec−1; however, the ...

The hydrogen evolution reaction and hydrogen oxidation reaction on thin film PdAu alloy surfaces
Physical Chemistry Chemical Physics, 2010A high throughput synthetic and screening methodology has been applied to the study of the Hydrogen Evolution Reaction (HER) and Hydrogen Oxidation Reaction (HOR) activities of PdAu thin film alloy surfaces. A compositional gradient method has been used to produce non-equilibrium surfaces of PdAu solid solution alloys.

Reactions at a Porous Ni Electrode Concurrent with Hydrogen evolution
ECS Transactions, 2008We summarize some of the difficulties we had in understanding the behavior of Ni electrodes, and Raney Ni in particular, in the hydrogen evolution reaction. We give a preliminary presentation of a set of experiments where the behavior of smooth or porous electrodes are compared after being conditioned with different protocols of polarization or of ...

The Mechanism of the Cathodic Hydrogen Evolution Reaction
Journal of The Electrochemical Society, 1952Some of the outstanding problems of concept and mechanism in the field of cathodic hydrogen evolution kinetics are discussed and clarified. A full derivation and correlation of kinetic equations which assume no mechanism reveals expressions for several parameters which take values specific to one or more mechanisms.

Theory of electrochemical hydrogen evolution reactions
Journal of Electroanalytical Chemistry and Interfacial Electrochemistry, 1979Abstract A model of electrochemical hydrogen ion discharge and hydrogen desorption processes (reactions I and II, respectively) is developed which combines the principal features of the Marcus-Levich-Dogonadze theory of electron transfer in a polar medium and the theory of electron transfer into reaction complex applied by Gurney, Butler and Bockris ...
