The calcination of a TiO(acac)(2)/Mn(acac)(3)/epoxy resin complex under an oxygen atmosphere successfully produced nano-sized TiO2/MnO2/carbon clusters composite material. The surface characterizations of the resulting composites indicate that they are composed of nano-sized particles of TiO2, MnO2 and carbon clusters. ESR spectral examination suggests the possibility of an electron transfer in the process of MnO2 -> carbon clusters -> TiO2. The visible light-responsive oxidation-reduction function of the composite materials has also been confirmed. (C) 2009 Elsevier B.V. All rights reserved.
