description The presence of pharmaceutical emerging pollutants in water can result in severe negative consequences on the environment and animal and human health. Among the different technologies to degrade these organic compounds, advanced oxidation techniques have attracted great interest in the scientific community, with special remark to solar photocatalysis which can be applied directly with solar light and without any addition of chemical compounds. In the current study, the photodegradation of acetaminophen, as model pharmaceutical emerging pollutant, under simulated solar irradiation was investigated using titania-based fibers prepared by the electrospinning technique, this offers an operational advantage considering its ease of separation from the reaction medium once the contaminant is degraded. The fibers were calcined at two different temperatures, 350 and 500 ⁰ C, which resulted in substantial differences in their physicochemical properties. Characterization revealed that the fibers calcined at the lower temperature exhibited higher porosity (A 2 BET >75 m /g), a carbon- rich surface composition (ca. 20 % measured by XPS) and a distinct crystallographic structure.
