Summary: The growing problem of environmental contamination, especially in soil and water, is mainly caused by rapid population growth, urban expansion, and industrial development. Traditional remediation techniques are often ineffective in removing chemicals, leading to a demand for new approaches in water remediation. Photocatalysis, particularly using titanium(IV) oxide nanoparticles, has been considered as a potential solution for degrading chemical pollutants like drugs.

Summary: Semiconductor-mediated photocatalysis is crucial for removing organic pollutants from water systems. TiO2 and ZnS semiconductor photocatalysts are commonly used in water purification, but their limitations hinder large-scale applications. Binary and ternary TiO2/ZnS nanostructured materials offer a promising solution to enhance photoefficiency. This review discusses the development of TiO2/ZnS composites and the modification of ternary photocatalysts for wastewater treatment. The performance of engineered TiO2/ZnS-based ternary nanostructured materials is examined, along with synthetic routes, factors influencing photocatalytic performance, and future research opportunities.

Summary: In recent times, a wide range of toxic organic contaminants have been released into natural water resources, making the removal of these pollutants before they are discharged into water bodies crucial. Various techniques have been employed for removing these pollutants, and advanced oxidation photocatalytic methods using zinc oxide (ZnO) nanoparticles have been commonly utilized as an effective catalyst for contaminated water treatment. However, the wide energy gap of ZnO, which can only be activated under ultraviolet (UV) light, and the high recombination of electron-hole pairs limit its photocatalytic performance.

Summary: Chemical hydrogen storage is essential for establishing hydrogen as a main energy vector. Liquid organic hydrogen carriers (LOHCs) offer the advantage of safe, efficient, and high-density hydrogen storage. In this study, molecular simulations were used to estimate the properties of potential LOHCs and evaluate the performance of binary mixtures. The results suggest that certain pairs, such as 1-methylnaphthalene/1-methyldecahydronaftalene and methyl-benzylpyridine/perhydromethylbenzylpyridine, are suitable candidates for chemical hydrogen storage.

Summary: Microplastic contamination in marine ecosystems poses a growing concern due to its trophic transfer and negative effects on marine organisms. This study investigates the transfer and impacts of polystyrene microplastics in an estuarine food chain. The results show that microplastics can be transferred through the food chain, although the transfer rates are low. The exposed organisms exhibit stress responses, suggesting the potential risk of microplastics reaching humans through the food chain.
