Photodegradation of Aquaculture Antibiotics Using Carbon Dots-TiO Nanocomposites.

In this work, carbon dots (CD) were synthesized and coupled to titanium dioxide (TiO) to improve the photodegradation of antibiotics in aquaculture effluents under solar irradiation. Oxolinic acid (OXA) and sulfadiazine (SDZ), which are widely used in aquaculture, were used as target antibiotics. To prepare nanocomposites of CD containing TiO, two modes were used: in-situ (CD@TiO) and ex-situ (CD/TiO).
