摘要
Nano- structured TiO2/carbon clusters/Cr2O3 composite material has been successfully obtained by the microwave treatment of a TiO(acac)/Cr(acac)(3)/epoxy resin complex. The compositions of the composite materials were determined using ICP, elemental analysis and surface characterization by SEM-EDX, TEM and XRD. ESR spectral examinations suggest the possibility of an electron transfer in the process of TiO2 --> carbon clusters --> Cr2O3 with an oxidation site at TiO2 particles and a reduction site at Cr2O3 particles. The preliminary experimental results show that the calcined materials could decompose methylene blue under visible-light irradiation. (C) 2008 Elsevier B.V. All rights reserved.
