摘要：

Na5PV2Mo10O40 supported on nanoporous anatase TiO2 particles, TiO2-PVMo, was used as an efficient photocatalyst for photocatalytic degradation of different dyes by visible light using oxygen as oxidant. This catalyst showed a good catalytic activity in the sonocatalytic and sonophotocatalytic decomposition of different dyes in aqueous solutions. The TiO2-PVMo composite showed higher photocatalytic and sonocatalytic activity than pure polyoxometalate or pure TiO2. (C) 2007 Elsevier B.V. All rights reserved.
