Theoretical Description for an Efficient Rhenium Electrocatalytical Recuperation by Polypyrrole Overoxidation

An interesting process for rhenium recuperation during the polypyrrole overoxidation has been theoretically described. The correspondent mathematical model has been developed and analyzed using linear stability theory and bifurcation analysis. The model's analysis confirms the possibility for the efficient rhenium ion capture by polypyrrole overoxidation, yielding a long-living electrocatalytic material. On the other hand, oscillatory instability is also possible in both stages.
