Intercalation of methylene blue into layered titanic acid H2Ti4O9 was examined by a guest exchange method using a propylammonium-HxTi4O9 intercalation compound as the intermediate. Methylene blue cations were arranged in the interlayer space obliquely to the layer surface. The visible spectrum of the intercalation compound suggested that the methylene blue cations were in an associated state in the interlayer space of H2Ti409. The intercalated methylene blue cations underwent a reversible electrochemical redox reaction in the dark, indicating that intercalation compounds of H2Ti4O9 can be applied to a modified electrode.
