Electrospun Nanofiber Dopped with TiO₂ and Carbon Quantum Dots for the Photocatalytic Degradation of Antibiotics.

ABSTRACT: Novel photocatalysts were synthesized through the association of carbon quantum dots (CQDs) with commercial (P25) titanium dioxide (TiO₂) by sonication. The resulting TiO₂/CQDs composite was then incorporated into the polyamide 66 (PA66) biopolymer nanofibers using the electrospinning technique, considering a composite nanoparticles-to-polymer ratio of 1:2 in the electrospinning precursor solution. The produced nanofibers presented suitable morphology and were tested for the photocatalytic degradation under simulated solar radiation of 10 mg L^-1 of amoxicillin (AMX) and sulfadiazine (SDZ), in phosphate buffer solution (pH 8.06) and river water, using 1.5 g L^-1 of photocatalyst. The presence of the photocatalyst increased the removal of AMX in pho
