The hydrogen-evolution reaction: Influence of zeta potential and surface heterogeneity on Tafel slopeExpressions are derived for the cathodic Tafel slope as a function of both zeta potential and surface heterogeneity. The Tafel slope is shown to depend on the rate of change of zeta potential with ...
2.2.4 Hydrogen evolution As mentioned previously, the standard reduction potential of Zn/ZnO in Eq. (4) is −1.26 V (vs SHE at pH of 14), which is lower than that of the hydrogen evolution reaction (HER, Eq. (5), −0.83 V vs SHE at pH of 14). Hydrogen evolution reaction: ...
A hydrogen evolution reaction is the production of hydrogen through the process of water electrolysis. The evolution of hydrogen is possibly limited and based on the desorbing of molecules coming from the cathode surface. Hydrogen evolution usually occurs on metals such as: Platinum Copper Iron Moni...
文献中常见的析氢反应方程如下H3O++e−=Hads+H2OHads+H3O++e−=H2+H2O这是在酸性溶液中,溶液要满足电中性的话,失去正离子H+的同时也要失去同样电荷数的阴离子,这个阴离子是怎么反应的?
Recently, monolayer molybdenum disulphide (MoS2) has emerged as a promising and non–precious electrocatalyst for hydrogen evolution reaction. However, its performance is largely limited by the low density and poor reactivity of active sites within its basal plane. Here, we report that domain boundari...
Platinum (Pt)-based catalysts are generally considered to be the most effective electrocatalysts for the hydrogen evolution reaction (HER)5,7. Unfortunately, Pt is expensive and scarce, limiting the commercial potential for such catalysts. The development of active, stable and inexpensive electrocatalyst...
The hydrogen evolution reaction ( her ) was studied on bright nickel electrodes in alkaline solutions at several temperatures. The formation of nickel hydrides in the potential region of the her was previously analyzed by cyclic voltammetry and the electrode surface was pre-conditioned to minimize the...

Usually, an increase in the applied potential and the surface area of the active material with the presence of certain impurities in the electrode could cause a rise in hydrogen evolution reaction (HER), not oxygen evolution reaction (OER). This includes a decrease in the overpotential that can...
The cathodic reaction is called hydrogen evolution reaction (HER), which includes the reduction of H2O or protons to form molecular H2.
