Electrolytic D/H isotope separation efficiency and electrocatalytic activity of Mo-Pt intermetallic phases
Apstrakt
The aim of this work was to investigate efficiency of the electrolytic separation of hydrogen isotopes (D/H), from alkaline 6 M KOH solution as standard electrolyte, on the Mo-Pt intermetallic phases as cathode materials. We measured the isotope separation factor (alpha) of the single-stage process, as a basic parameter determining the isotope separation efficiency. Furthermore, we have found that some combinations of activating compounds (ionic activators added directly into the electrolyte, assuming in situ activation) can reduce energy needs per mass unit of hydrogen produced, as well as the isotope separation efficiency, compared to those of the standard electrolyte. Also, the electrocatalytic ability of Mo-Pt intermetallic phases for the hydrogen evolution was investigated and evaluated at fixed over-potential (energy input) trough measured current density. Such investigations offer a possibility to optimize the electrolytic process, based on a significant upgrade of the efficienc...y regarding two needs: hydrogen production and isotope separation.
