“…The development of efficient, low-cost, and environmentally friendly photocatalysts has attracted the interest of researchers for a series of applications, including production of "green fuels", [1][2][3] and water remediation from polluting dyes and drugs. [4] Water contamination is one of the upfront issues to be solved. [5] Complex organic molecules and pharmaceuticals including antibiotics are gaining attention due to their abuse and their low degradability.…”

Nanostructured TiO 2 is one of the best materials for photocatalysis, thanks to its high surface area and surface reactivity, but its large energy bandgap (3.2 eV) hinders the use of the entire solar spectrum. Here, it is proposed that defect-engineered nanostructured TiO 2 photocatalysts are obtained by hydrogenation strategy to extend its light absorption up to the near-infrared region. It is demonstrated that hydrogenated or colored TiO 2 hollow spheres (THS) composed of hierarchically assembled nanoparticles result in much broader exploitation of the solar spectrum (up to 1200 nm) and the engineered surface enhances the photogeneration of charges for photocatalytic processes. In turn, when applied for photodegradation of a targeted drug (Ciprofloxacin) this results in 82% degradation after 6 h under simulated sunlight. Valence band analysis by photoelectron spectroscopy revealed the presence of oxygen vacancies, whose surface density increases with the hydrogenation rate. Thus, a tight correlation between degree of hydrogenation and photocatalytic activity is directly established. Further insight comes from electron paramagnetic resonance, which evidences bulk Ti 3+ centers only in hydrogenated THS. The results are anticipated to disclose a new path toward highly efficient photocatalytic titania in a series of applications targeting water remediation and solar fuel production.

“…P2 and P3 could further transform during photocatalytic oxidation to generate P4 ( m / z = 349). 66,67 For degradation pathway 3, TCH was decomposed to P5 ( m / z = 417) successively by losing two methyls under the oxidation of ˙O 2 − . 68 Finally, these intermediates can be degraded and converted into inorganic ions such as CO 2 and H 2 O under further oxidation.…”
