Studies of N-demethylation oxidative and degradation of methylene blue by thin layers of birnessite electrodeposited onto SnO2

▶ Interest of using thin layer for understanding mechanism at solid-liquid interfaces. ▶ Study of spontaneous reactivity of birnessite towards phenothiazine dyes. ▶ Rapid degradation without supply energy. ▶ Increasing of mineralisation with interaction duration. ▶ Highlighting of the good spontaneous reactivity of a non-toxic material.
