Summary: The study established the influence of the crystalline phase and agglomeration degree of TiO2 nanoparticles on photocatalytic hydroxyl radical formation and bacterial inactivation in TiO2/SiO2 composite coatings. A relationship between hydroxyl radicals' formation and charge carrier transfer mechanism between defect levels in SiO2 and TiO2 embedded nanoparticles was established through a simple spectroscopic method. This correlation complements the lack of mechanisms behind the photocatalytic activity in TiO2/SiO2 composites.

Summary: The study demonstrates that marine phytoplankton are more sensitive to iron content in solid particles, especially ilmenite and hematite which have a positive impact on the growth of diatoms. Diatoms acquire iron from solid particles, with smaller growth responses when physically separated from dust particles. Additionally, diatoms benefit more from mineral dust particles in direct contact with cells.

Summary: This study investigates the removal of microcontaminants (MCs) using natural solar zero-valent iron (ZVI) process at natural pH in actual matrices. The results show that the addition of sulphates and iron chelate does not significantly affect the process efficiency, while the presence of carbonates in natural water reduces the treatment time. Moreover, the solar/microspheres ZVI/hydrogen peroxide and solar/microspheres ZVI/persulfate processes achieve a moderate removal efficiency for MCs in actual wastewater treatment plant secondary effluent.

Summary: Recently, there has been a focus on surface-defective titanium dioxide and black TiO2 due to their advanced optical, electrical, and photocatalytic properties. The synthesis of these materials for the degradation and mineralization of organic pollutants in water, especially under visible light, has attracted attention from both scientific and application perspectives. Chemical reduction by heating a TiO2 and NaBH4 mixture successfully introduced Ti3+ defects and oxygen vacancies at the surface of TiO2, enhancing its photocatalytic degradation efficiency for amoxicillin. Annealing temperature and reduction method play a crucial role in determining the properties of the TiO2 samples.

Summary: In this study, a solar electrochemical-raceway pond reactor (SEC-RPR) was used to treat textile industrial wastewater by solar photoelectron-Fenton (SPEF) for the first time. The experimental variables and optimal conditions for methyl orange removal, mineralization, and decolorization were investigated. The results showed that the SPEF process using SEC-RPR achieved high mineralization rates and complete decolorization. The study also proposed a reaction pathway for the mineralization of methyl orange. This work is an important step towards the development of a demo-scale SEC-RPR.

Summary: The direct or indirect discharge of toxic and non-biodegradable organic pollutants into water poses a significant threat to human health and the environment. Hence, the utilization of sustainable technologies for wastewater treatment is crucial for reuse. Photocatalysis, a highly innovative advanced technique, is regarded as an effective method for pollutant removal from wastewater due to its efficiency, simplicity, affordability, and environmentally friendly byproducts. Photocatalysis relies on carefully selecting catalysts, typically semiconductor materials with high solar light absorption capacity and conductivity for photogenerated charge carriers. Among copper sulfides, CuS (covellite), as a semiconductor with diverse morphologies and bandgap values, stands out as an essential photocatalyst for eliminating various organic pollutants (e.g., dyes, pesticides, pharmaceuticals) from wastewater. This review explores recent advancements in the photodegradation of organic pollutants using various CuS nanostructures, including CuS NPs, CuS QDs, and heterojunctions (CuS/carbon-based materials, CuS/organic semiconductors, CuS/metal oxides). The impacts of different synthesis parameters (Cu:S molar ratios, surfactant concentration, etc.) and properties (particle size, morphology, bandgap energy, surface properties) on the photocatalytic performance of CuS-based catalysts for degrading different organic pollutants are extensively discussed.

Summary: This study focuses on understanding the interactions between a complex water matrix and the process of removing a mixture of microcontaminants (acetamiprid, carbamazepine, and caffeine) using the solar/Fe3+-EDDS/persulfate process. The effects of sulfates, nitrates, bicarbonates, and chlorides on the process were assessed in different synthetic and actual water samples. The results showed that bicarbonates and chlorides have a significant impact on the efficiency of microcontaminant removal in complex water matrices, while dissolved organic matter had a negative effect on removal efficiency depending on its concentration and composition.

Summary: Solar driven advanced oxidation processes (S-AOPs) have been successfully studied as tertiary and quaternary treatment of urban wastewater. However, their application has been hindered by the lack of comparison data with consolidated technologies and evaluation of environmental impact. This study compared the environmental impact of a new S-AOP called sequential treatment (ST) with sunlight/H2O2 and solar photo-Fenton (SPF) to pilot scale ozonation (O-3) treatment through Life Cycle Assessment (LCA). The results showed that ST had a better overall environmental performance compared to O-3, making it a more sustainable solution for small urban wastewater treatment plants.
