Reduced graphene oxide and PbS nanoparticles co-modified TiO2 nanotube arrays as a recyclable and stable photocatalyst for efficient degradation of pentachlorophenol
TL;DR: In this paper, reduced graphene oxide (RGO) and PbS nonoparticles (NPs) were simultaneously modified by a simple one-step electrodeposition process, and the photocatalytic activity of the ternary RGO/PbS-TiO 2NTs photocatalyst far exceeds those of bare TiO 2 NTs.
Journal ArticleDOI
Application of solar photocatalytic ozonation for the degradation of emerging contaminants in water in a pilot plant
TL;DR: In this paper, the authors compared different solar-driven photochemical processes including photolysis, photocatalytic oxidation with Fe(III) or TiO2, photo-Fenton and single, photolytic and photocatallytic ozonations in a compound parabolic collector photoreactor.

Removal of pharmaceuticals at microg L 1 by combined nanofiltration and mild solar photo-Fenton
TL;DR: In this article, Nanofiltration (NF) membranes were used for treating water containing pharmaceuticals, discharging a permeate practically free of contaminants, and the concentrate was treated with mild solar photo-Fenton operated at pH 5 − 6, low iron (5 ǫ 2+ Â l − 1 ) and hydrogen peroxide concentrations ( − 1 ).
