Electrocatalysts for oxygen evolution in advanced water electrolysis

Thermodynamic and electrochemical properties of nanocrystalline Mg2Cu-type hydrogen storage materials

“…After each cycle the electrodes were subjected to relax- ation (0.5 h) at open circuit and then the measurements were continued. The relation between the hydrogen equilibrium pressure and the amount of hydrogen absorbed in the alloy electrodes was determined on the basis of the Nernst equation according to the procedure reported by Balej [15], which takes into account the coefficient of hydrogen volatility:…”

Electrodeposited Ni-Sn coatings as electrocatalysts for hydrogen and oxygen evolution in alkaline solutions

“…Therefore, the presence of higher oxides than β-NiOOH (O/Ni = 1.5) is possible. Srinivasan et al [12] [10]; (b) by applying an electrode with a highly developed surface area in order to maintain the anode potential below the critical value of 1.56 V at the required current density (Raney-Ni anodes) [28]; (c) by alloying of Ni-oxides [29][30][31][32][33][34]; (d) by pigmenting Ni coatings with Ru and/or Ir nanoparticles-composite electrocatalysts [35].…”
