The electronic behaviors of TiO2/MnO2/carbon clusters composite materials obtained by the calcination of a TiO(acac)2/Mn(acac)3/epoxy resin complex

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.
