Abstract

Photodegradation of methylene blue (MB) on TiO2 in presence of activated carbons (AC) was studied. Apparent first order rate constant for the degradation of MB was higher in presence of any AC indicating that the binary materials TiO2-AC showed a clear enhancement in the photocatalytic activity relative to TiO2 and this enhancement was associated with the properties of AC.
