In this study, carbon nanotubes (CNTs)TiO(2) Composite were prepared and the sonophotocatalytic activity of CNTs/TiO(2) nanoparticles was investigated, in which methyl orange (MO) was chosen as an object. The results indicate that the photocatalytic efficiency of CNTs/TiO(2) remarkable increases in the presence of ultrasound, and the sonophotocatalysis process followed a first-order kinetics. The kinetic constant of CNTs/TiO(2) for the MO degradation is 2.2 times higher than that of P25, which indicated that the sonophotocatalytic ability of CNTs/TiO(2) is obviously higher than P25 powder.
