It appears that even in a catalytic mechanism for ferricyanide decomposition, Fe 3+ coordination is likely to be an important step. Another possible contribution to the ferricyanide losses could be the single-electron reduction of the deprotonated hydroxyl group by ferricyanide. Ferricyanide can oxidize phenols in alkaline conditions, which could explain why highest ferricyanide losses are seen in the presence of the hydroxyl functionalized anolytes, DHPS and 2,6-DHAQ. Together, there is evidence that there are multiple mechanisms involved in the crossover-driven side reactions observed. Further work should be carried out to gain more insight into the nature of these mechanisms, especially using EPR to determine if there are any radical intermediates or any complexes where 2,6-DHAQ is coordinated to paramagnetic iron complexes. Determining the exact nature of these mechanisms will help improve our understanding of these side reactions, which would further aid the development of improved ferrocyanide-based batteries.
