Effect of temperature on kinetics of the hydrogen evolution reaction on Ni-P-C cathodes in alkaline solution
The kinetics of hydrogen evolution reaction (HER) was studied in 1M NaOH at various temperatures (298 to 358 K) on Ni-P-C (composite electrodes. The electrochemical efficiency of the electrodes has been evaluated on the basis of electrochemical data obtained from the steady-state polarization Tafel curves, electrochemical impedance spectroscopy (EIS) and cyclic voltammetry (CV) in 1M NaOH solut...

متن کاملNi-MoO2 cathodes for hydrogen evolution in alkaline solutions. Effect of the conditions of their electrodeposition
The electrodeposition of Ni-MoO2 composite coatings is a specific process taking place under defined hydrodynamic conditions. In this work the influence of hydrodynamics, current density, and MoO2 concentration on the electrodeposition of Ni-MoO2 coatings from a suspension of MoO2 particles in a Watt’s type bath were investigated by comparison of their polarization characteristics for the hydro...
متن کاملThe effect of hydrogen evolution reaction on conductance quantization of Au, Ag, Cu nanocontacts.
We have mechanically fabricated Au, Ag, and Cu nanocontacts in solution under electrochemical potential control. At the hydrogen evolution potential, fractional conductance peaks appeared near 0.5 G(0) (G(0) = 2e(2)/h) in the conductance histogram of Au and Cu. This fractional conductance peak was not observed in the conductance histogram of Ag. In the case of Au nanocontacts in 50 mM H(2)SO(4)...

We have mechanically fabricated Au, Ag, and Cu nano contacts in solution under the electrochemical potential control. At the hydrogen evolution potential, fractional conductance peaks appeared near 0.5 G0 (G0=2e/h) in the conductance histogram of Au and Cu. This fractional conductance peak was not observed in the conductance histogram of Ag. In the case of Au nano contacts in 50 mM H2SO4 soluti...
