Photocatalytic activity of TiO2 nanofibers in simulated and real municipal effluents
TL;DR: In this article, the performance of H-titanate nanofiber (NF) and commercial Degussa P25 (P25) catalysts was evaluated in a laboratory scale photo-reactor.

A life cycle assessment of solar-based treatments (H2O2, TiO2 photocatalysis, circumneutral photo-Fenton) for the removal of organic micropollutants.
TL;DR: The solar TiO2-P25 treatment, which was here investigated by LCA for the first time to remove organic micropollutants from secondary-treated urban wastewater, appears to be the most suitable option at the studied conditions.
Journal ArticleDOI
Virus inactivation by high frequency ultrasound in combination with visible light
TL;DR: The simultaneous use of US and VL was found to be more effective than US alone for MS2 inactivation, indicating the existence of a synergistic effect, however, the use of VL in conjunction with high frequency US hindered the inactivation of ΦX174.

Solar or UVA-Visible Photocatalytic Ozonation of Water Contaminants
TL;DR: An incipient advanced oxidation process, solar photocatalytic ozonation (SPO), is reviewed in this paper with the aim of clarifying the importance of this process as a more sustainable water technology to remove priority or emerging contaminants from water.

TiO2 photocatalysis and related surface phenomena
TL;DR: The field of photocatalysis can be traced back more than 80 years to early observations of the chalking of titania-based paints and to studies of the darkening of metal oxides in contact with organic compounds in sunlight as discussed by the authors.
