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.

Modulation of Phosphorene for Optimal Hydrogen Evolution Reaction
ACS Applied Materials & Interfaces, 2019Economical and highly effective catalysts are crucial to the electrocatalytic hydrogen evolution reaction (HER), and few-layer black phosphorus (phosphorene) is a promising candidate because of the high carrier mobility, large specific surface area, and tunable physicochemical characteristics.

Pristine Graphene Electrode in Hydrogen Evolution Reaction
ACS Applied Materials & Interfaces, 2017Graphene, the sp2 carbonaceous two-dimensional (2D) material, is gaining more attention in recent electrochemical studies. However, this atomic thick electrode usually suffers with surface contamination and poor electrochemical endurance. To overcome the drawbacks, we developed a PMMA-assisted, flipped transfer method to fabricate the graphene ...

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 on the Hydrogen Storage Alloy Electrode
Journal of Electrochemistry, 1998The hydrogen evolution reaction was studied in 1 mol/L KOH solution on the hydrogen storage alloy Mm(NiCoMnAl)5 electrode using open circuit potential decay and ac impedance technique. The reaction was found to proceed by the Volmer(discharge)-Tafel(recombination)mechanism.

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.
