Effects of sunscreens on plants: Impact of TiO2 nanoparticles on the phytoremediation of oxybenzone
(Corresponding) Schröder P., Chen F.
Topic:
Emerging pollutants
Increasing levels of sunscreens have been found in surface waters, and in waste water. In most cases mixtures of organic and inorganic sunscreen compounds can be detected. Wetland plants, and vegetation along shores have been used as biological filters for this kind of pollution along beaches, and...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

Silver decorated TiO2/g-C3N4 nanocomposites for photocatalytic elimination of water pollutants under UV and artificial solar light
Ibrahim I., Belessiotis G., Kaltzoglou A., Katsaros F., Salama T., (Corresponding) Falaras P.
Topic:
Water treatment
TiO2/g-C3N4/Ag nanocomposites were prepared and used as highly efficient photocatalysts. TiO2 nanoparticles were first prepared using a sol-gel process, and titania herostructures with varying amounts of graphitic carbon nitride (g-C3N4) were created using a hydrothermal technique. Following...Read more

(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
Influence of the addition of M2+ (M: Co, Cu, Zn) on the properties and activity of W-TiO2 and Mo-TiO2 photocatalysts for water remediation
Mergenbayeva S., (Corresponding) Poulopoulos S., Grilla E., Vakros J., Mantzavinos D.
Topic:
Advanced oxidation processes
In this study, ternary systems of M1M2TiO2 (M1:Co, Cu, Zn) M2 (WO3, MoO3) were prepared and tested for the photocatalytic degradation of sulfamethoxazole. It was found that W-oxo species can be used without significant alteration of the TiO2 activity, while only Cu is a possible candidate for the...Read more
Removal Of Ciprofloxacin From Waste Water By Photocatalytic Method With Waste Polystyrene And Tio2 Composites
(Corresponding) Hayri-Senel T., Kahraman E., Sezer S., Erdol-Aydin N., Nasun-Saygili G.
Topic:
Wastewater treatment
Ciprofloxacin (CIP) is one of the widely used antibiotics. Since ciprofloxacin in the aquatic ecosystem adversely affects human health as well as other organisms, it must be removed from wastewater.
The aim of this study was to develop polystyrene (PS) and TiO2 composites that can be used as...Read more
