N,S co-doped TiO2 nanoparticles and nanosheets in simulated solar light for photocatalytic degradation of non-steroidal anti-inflammatory drugs in water: a comparative study

摘要

BACKGROUND: In this study, highly visible-light photoactive nitrogen and sulfur co-doped TiO2 (N, S-TiO2) nanoparticles and nanosheets were synthesized via facile sol-gel and hydrothermal methods, respectively. The photocatalytic activities of N, S-TiO2 catalysts were evaluated by degradation of non-steroidalanti-inflammatory drugs, ibuprofen(IBP) andnaproxen(NPX), under simulated solar irradiation.
