The photodegradation of phenol under visible light by using TiO₂ and activated carbon prepared by physical activation was performed. Activated carbon was prepared from Tabebuia Pentaphyla wood by physical activation under CO2flow at 800ºC. UV-Vis lamp with a high proportion of visible light was used. Kinetic results of phenol photodegradation indicated a beneficial effect between TiO₂and AC. An increase of apparent first-order rate constant (k_app) by a factor of 1.74 in presence of TiO₂-AC was obtained in comparison than TiO₂ alone. This cooperative effect between both solids was ascribed to the high surface area and basic surface pH of this type of AC.
