Visible light induced degradation of methylene blue on titanium oxo ethoxo clusters of type Ti₁₆O₁₆(OEt)₃₂

Titanium-oxo-ethoxo cluster, Ti₁₆O₁₆(OEt) ₃₂ (Ti₁₆-cage) has been used as a nano-building block for advanced materials. Photocatalytic application may also be possible due to its molecular structure consisting of an inorganic titanium oxide core. However, the Ti₁₆-cage is too unstable to examine its photocatalytic properties under atmospheric conditions. Herein it is shown for the first time that the aforemen-tioned Ti16-cage is capable of/can be used for the degradation of organic dyes under visible light irradiation. A possible mechanism of this photocatalytic reaction is proposed.
