摘要
A new nanostructure based on TiO2, activated carbon and silver nanoparticles is synthesized in this work. The optical and morphological characterization of the nanoparticles is performed with well-established physicochemical-techniques. The photocatalytic properties of TiO2 are improved with activated carbon and extended to visible radiation with a silver nanoparticles doping. The synergy of the three materials to enhance biocide activity is successfully demonstrated in vitro in cultures of bacteria and algae and in aquatic controlled environments. This activity is supposed to be due to the augmentation in the superoxide and hydroxyl radicals in the presence of activated charcoal.
