Degradation of phenol in photo-Fenton process by phosphoric acid modified kaolin supported ferric-oxalate catalyst: Optimization and kinetic modeling
TL;DR: In this paper, the degradation process was optimized to minimize the superfluous scavenging effect of excess dosage of hydrogen peroxide (HP) and AMKC on the kinetics study, and the degradation was achieved without initial pH adjustments to avoid the interference of buffering on the degradation kinetics.

Enhancement of a solar photo-Fenton reaction with ferric-organic ligands for the treatment of acrylic-textile dyeing wastewater.
Petrick Anderson Soares,Mauro Batalha,Selene M.A. Guelli U. de Souza,Rui A.R. Boaventura,Vítor J.P. Vilar +4 more
TL;DR: It is elucidated that the slow decay on DOC concentration is associated with the formation of stable complexes between Fe(3+) and textile auxiliary products, limiting the photoreduction of Fe( 3+).

Influence of Aqueous Inorganic Anions on the Reactivity of Nanoparticles in TiO2 Photocatalysis
Jeffrey Farner Budarz,Andrea Turolla,Aleksander F. Piasecki,Jean-Yves Bottero,Manuela Antonelli,Mark R. Wiesner +5 more
TL;DR: This work shows that the reactivity of NPs will be strongly influenced by the makeup of the waters they are released into, which arises from the interplay of several physicochemical phenomena.

Photocatalytic degradation of model pharmaceutical pollutant by novel magnetic TiO2@ZnFe2O4/Pd nanocomposite with enhanced photocatalytic activity and stability under solar light irradiation.
TL;DR: The findings showed that after five recycles, the photocatalytic efficiency of TiO2@ZnFe2O4/Pd nanocomposite in diclofenac photodegradation did not show much reduction i.e. the removal efficiency from 86.1% in the first cycle reduced only to 71.38%" in the last cycle.

Visible-Light Photocatalysis in Nitrogen-Doped Titanium Oxides
TL;DR: Film and powders of TiO2-x Nx have revealed an improvement over titanium dioxide (TiO2) under visible light in optical absorption and photocatalytic activity such as photodegradations of methylene blue and gaseous acetaldehyde and hydrophilicity of the film surface.

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.
