POLLUTANT PHOTO-NF REMEDIATION OF AGRO-WATER
(Corresponding) Romanos G., Falaras P., Markellou E., Georgaki I., Kizis D., Karanasios E., Anagnostopoulous C.
Topic:
Water treatment
The agro-food industry is the main manufacturing industry in Europe, representing 14% of the total turnover and accounting for approximately 1.8% of Europe’s total water use. The absence of effective wastewater management approaches can lead to potential ecological ramifications including...Read more

Evaluation of Photocatalytic Materials for Water Purification: Overview of the New CEN Standard Test
Triantis T., Kaloudis T., (Corresponding) Hiskia A.
Topic:
Water treatment
TiO2 photocatalysis offers an attractive alternative to conventional water treatment technologies leading directly to the degradation of organic pollutants, compared to transferring them from one phase to another as in the case of membranes or activated carbon. There is an increasing interest on...Read more

Fluoride-free Anodization of Titanium and the Photocatalytic Behaviour the Produced TiO2 Nanostructures
Taylor C., (Corresponding) Wenk J., Mattia D.
Topic:
Advanced oxidation processes
Current methods for anodizing titania to produce immobilized titanium dioxide (TiO2) photocatalyst require the use of hazardous fluoride electrolytes. A fluoride-free electrolyte anodization method was developed. The electrolytes tested in this study were both bromide- and chloride-based and...Read more
Structuring efficient photocatalysts into bespoke fiber shaped systems for applied water treatment
(Corresponding) Theodorakopoulos G., Romanos G., Katsaros F., Papageorgiou S., Falaras P., Kontos A., Beazi-Katsioti M.
Topic:
Nanomaterials in the environmnents applications and effects
In this study structured photocatalytic systems were successfully developed by a facile method. Polymeric (Alginate) molds, settled the basis in order to effectively disperse and stabilize nanoparticles of an efficient, copper augmented photocatalyst (Degussa P25), which after removal of the...Read more

Bacterial inactivation and study of damages in subcellular level during disinfection of aqueous samples
(Corresponding) Gounaki I., Lironi M., Venieri D.
Topic:
Advanced oxidation processes
The objectives of the current study were i) to investigate the effectiveness of ozonation and UVA photocatalysis for the inactivation rate of representative bacterial strains, which are considered important for public health and ii) to study damages in subcellular level, in terms of disinfection...Read more
TiO2/Graphene Oxide Heterostructures for Photocatalytic Applications
(Corresponding) Giannakopoulou T., Papailias I., Todorova N., Trapalis A., Bahnemann D.
Topic:
Nanomaterials in the environmnents applications and effects
In the present work, TiO2/graphene oxide (GO) heterostructures with different concentrations of GO were synthesized by hydrothermal transformation of Na-titanate in basic solution. The morphology of the prepared materials was observed by X-ray diffraction analysis (XRD) and transmission electron...Read more

In our study a combination of Palygorskite clay mineral with TiO2 nanoparticles used for the decomposition of the common tebuconazole (TEB), C16H22ClN3O, [(RS)-1-p-chlorophenyl-4,4-dimethyl-3-(1H-1,2,4-triazol-1-ylmethyl)-pentan-3-ol], fungicide in water. For this purpose, Palygorskite-TiO2...Read more
Immobilized rGO/TiO2 photocatalyst for water purification
Zouzelka R., Brabec L., Remzova M., (Corresponding) Rathousky J.
Topic:
Advanced oxidation processes
The preparation of immobilized graphene–based photocatalyst layers is highly desired for environmental applications. In this study, the preparation of an immobilized reduced graphene oxide (rGO)/TiO2 composite by electrophoretic deposition (EPD) was optimized. It enabled quantitative deposition...Read more

Investigation of variables affecting UV-LED photocatalytic degradation of antibiotics ciprofloxacin and sulfamethoxazole
(Corresponding) Bertagna Silva D., Buttiglieri G., Babić S.
Topic:
Advanced oxidation processes
In this study, photolytic and photocatalytic degradation of two antibiotics in ultra-pure water were analyzed. A lab-scale cylindrical reactor had its inner walls impregnated with TiO2 nanofilm for the photocatalytic experiments. In the first step, an optimized photoreactor design was chosen based...Read more
TiO2/Fe2O3 based Composites for Solar-driven Photocatalytic Degradation of Amoxicillin
(Corresponding) dela Rosa F., Papac J., Kovačić M., (Corresponding) Kušić H., Božic A.
Topic:
Advanced oxidation processes
The occurrence of trace amounts of antibiotics in various bodies of water was directly linked to the development of antibiotic resistant pathogens. Recently, Amoxicillin (AMX) was added on the second EU “watch list” based on the proposed European Decision 2018/840/EU. Its presence in drinking water...Read more
