Kinetics study of the MO adsorption and photocatalytic degradation using an effectively engineered HF photocatalyst
(Corresponding) Theodorakopoulos G., Katsaros F., Papageorgiou S., Romanos G.
Topic:
Water treatment
In this study, copper decorated photocatalysts (Degussa P25), were shaped in the form of ceramic hollow fibers (HFs) and their photocatalytic properties were investigated using Methyl Orange (MO), a prototype anionic pollutant. The abatement of the dye was tested in dark and under UV irradiation by...Read more

Photocatalytic elimination of water pollutants using innovative titania thin film heterostructures embedding carbon quantum dots
(Corresponding) Falara P., Zourou A., Ibrahim I., (Corresponding) Kordatos K.
Topic:
Water treatment
Titanium dioxide based photocatalysis is a well-established advanced oxidation process (AOP) that recently has expanded its borders comprising advanced reduction processes (ARPs) as well. To enhance the photocatalytic activity, titania heterostructures embedding semiconductors, or clays, or...Read more
Ηexavalent chromium reduction in a photocatalytic membrane reactor in the presence of organic acids
(Corresponding) Sarasidis V., Kyriakou E., Plakas K., Karabelas A.
Topic:
Advanced oxidation processes
This study deals with the photocatalytic reduction of carcinogenic hexavalent chromium, encountered in industrial effluents and surface waters, to much less toxic and harmful trivalent form. Experiments were performed in a pilot scale Photocatalytic Membrane Reactor employing titanium dioxide...Read more
Photocatalytic Removal of Pesticides Present in Agro-industrial Water Effluents
Arfanis M., Theodorakopoulos G., Anagnostopoulos C., Georgaki I., Liappis K., Romanos G., Markellou E., (Corresponding) Falaras P.
Topic:
Wastewater treatment
Pesticide residues accumulated in agricultural wastewaters constitute a potential risk for the environment and the human health. Hence, focused actions for their elimination are of high priority for both the industry and national authorities. This work evaluates the effectiveness of the...Read more
Solar photocatalytic degradation of pharmaceutical compounds using ZnSnO3/CB composites
Kouvelis k., Petala A., (Corresponding) Frontistis Z., Kondarides D.
Topic:
Advanced oxidation processes
In this study, the activity of ZnSnO3 as a photocatalyst for the degradation of persistent micro–pollutants under simulated solar irradiation has been assessed. Zinc stannate (ZnSnO3), belongs to the class of ternary oxides and has a reported band gap of 2.4 eV. Due to its narrow band gap can be...Read more
Can mixed oxides act as efficient photocatalysts for the elimination of organic water pollutants?
(Corresponding) Favier L., Sescu A., (Corresponding) HARJA M., Siamer S., Lutic D.
Topic:
Advanced oxidation processes
New mixed-metal oxides containing zinc and lanthanum were prepared by coprecipitation. The synthesized nanocomposites were calcined, and characterized by scanning electron microscopy (SEM), X-ray diffraction, FT-IR, BET and DR analysis. The calcined sample showed a higher crystalinity, confirmed by...Read more
