Photocatalytic degradation of ibuprofen using titanium oxide: insights into the mechanism and preferential attack of radicals

“…The superoxide radicals formed react with the acid medium to form another radical species (HO 2 c), reaction (13). Reaction (14) describes the dimerization of the hydroperoxide radical, forming the hydrogen peroxide molecule, which decomposes into OHc and OH À species according to reaction (15). In addition, reaction (16) demonstrates the attack of the hydroxyl radical on activated ibuprofen species to drive their complete degradation.…”

“…The presence of the OHc radical was confirmed through a model reaction using salicylic acid as a probe molecule.À c) and hydroperoxide (HO 2 c) radicals to degrade the organic materials and mineralize the contaminant to carbon dioxide and water. [11][12][13][14] Heterogeneous photocatalysis…”

Electrocatalytic Degradation of Levofloxacin, a Typical Antibiotic in Hospital Wastewater

“…Considering the cathode, it is speculated that a large amount of hydrogen peroxide could be produced in both acidic and alkaline conditions, and hydrogen peroxide could easily quench the •OH generated on the anode, so the neutral conditions are better [47]. Considering the anode, it is speculated that in acidic solutions, the presence of HSO 4 − may quench the •OH, thereby reducing the degradation efficiency of LVX [48]. Alkaline conditions reduce the oxygen evolution overpotential and increase the side reaction of oxygen evolution.…”

Novel TiO2/TPU composite fiber-based smart textiles for photocatalytic applications

“…Since Hoda and Fujishima investigated water splitting into oxygen and hydrogen by TiO 2 under UV light irradiation, many intricate nanostructured and heterogeneous photocatalysts have been reported with high photocatalytic performances. 1–6 Currently, TiO 2 photocatalysis is actively used in the field of photodegradation of organic compounds, specifically in environmental decontamination of wastewater, which also suffers from some problems. 7–11 During practical application, photocatalysts exist as a powder in the water system, ensuring a high number of photoactive sites and optimizing mass transfer.…”
