Homogeneous and heterogeneous degradation of caffeic acid using photocatalysis driven by UVA and solar light
(2015)
Waste water from the wine industry is characterized by a high concentration of dissolved organic matter and the presence of natural phenolic compounds with low biodegradability. High concentrations of phenolic compounds ...
Photocatalytic activity of N, S co-doped and N-doped commercial anatase TiO2 powders towards phenol oxidation and E. coli inactivation under simulated solar light irradiation.
(Pergamon-elsevier Science Ltd, 2009-10-14)
Nitrogen and sulfur co-doped and N-doped TiO2 anatase TKP 102 (Tayca) were prepared by manual grinding with thiourea and urea, respectively, and annealing at 400 C. Both materials showed visible-light absorption as measured ...
Enhanced photocatalytic activity of silver vanadate nanobelts in concentrated sunlight delivered through optical fiber bundle coupled with solar concentrator
(Springer, 2020-02-01)
To date, sunlight driven photocatalytic process for wastewater treatment is a great challenge. Herein, the photocatalytic methylene blue (MB) dye degradation activity of silver vanadate nanobelts has been enhanced using ...
