3.5 Adsorption and photocatalytic activity of MC, TiO2
and TiO2/MC samples
The activities of the TiO2/MC nanocomposites were
evaluated by the photodegradation of MO aqueous solution
under UV irradiation. As a comparison, pure TiO2 was
prepared and its activity was also measured under the same
conditions. Fig. 6 showed the photocatalytic degradation rates
of MO by the TiO2/MC nanocomposites and pure TiO2 at 465
nm.
Compared with the removal rates of pure MC adsorption
and TiO2 photocatalytic degradation, the removal rates of MO
over the TiO2/MC nanocomposites are much high, owing to
the synergetic effect of adsorption and photocatalytic
