Summary: This study evaluated the ecological toxicity of aluminum oxide nanoparticles (Al2O3NP) on freshwater microalgae and its influence on the biodegradation of sulfacetamide. The results showed that Al2O3NP had limited toxicity on the microalgae, but its presence attenuated the toxicity of sulfacetamide. The microalgae still exhibited a stable biodegradation capacity for sulfacetamide even in the presence of Al2O3NP.

Summary: The study found that MnO2 has two different oxygen vacancies, and the catalytic decomposition efficiency of [Mn3+]-V0-[Mn3+] is significantly higher than that of [Mn3+]-V0. MnO2 with [Mn3+]-V0-[Mn3+] has a lower average oxidation state of Mn and faster electron transfer capacity. A new mechanism of ozone decomposition on [Mn3+]-V0-[Mn3+] was proposed.

Summary: In this paper, aluminum-doped zinc oxide (ZnO:Al or AZO) thin films were grown using atomic layer deposition (ALD), and the effects of postdeposition UV-ozone and thermal annealing treatments on the films' properties were investigated. X-ray diffraction (XRD) revealed a polycrystalline wurtzite structure with a preferable (100) orientation. Thermal annealing increased the crystal size, while UV-ozone exposure had no significant impact on crystallinity. X-ray photoelectron spectroscopy (XPS) analysis revealed a higher amount of oxygen vacancies in the ZnO:Al after UV-ozone treatment, while the ZnO:Al had lower oxygen vacancies after annealing. The important and practical applications of ZnO:Al were found, particularly for transparent conductive oxide layers with high tunability in electrical and optical properties after postdeposition treatment, especially UV-ozone exposure for reducing sheet resistance values. Meanwhile, UV-ozone treatment did not affect the polycrystalline structure, surface morphology, or optical properties of the AZO films.

Summary: In this study, Sn-modified alpha-MnO2 catalyst exhibited excellent oxidation activity for benzene, outperforming commercial hopcalite catalyst in terms of benzene conversion, CO2 production, water and NO2 resistance, and cyclability. The catalyst's easily accessible acid sites, abundant reactive oxygen vacancies, and weakened Mn-O bonds were crucial for the diffusion of benzene molecules and transportation of surface oxygen, leading to superior benzene abatement performance. Additionally, the SnMn composite also demonstrated good performance in ozone decomposition and PM2.5 filtration.

Summary: Ozonation of aromatic compounds in low-pH water is ineffective due to limited decomposition of ozone and inhibition by halogen ions. However, the presence of bromides can initiate self-enhanced ozonation, which can be inhibited by phosphates or sulphates. The addition of these inorganic salts helps recover ozone decomposition and degradation efficiency of benzoic acid.

Summary: Activated carbons are commonly used in water treatment as sorbents for removing organic impurities and as catalysts in the ozonation process. However, commercially available activated carbons are often contaminated by mineral substances, which significantly influence the properties of the carbons and their ozonation effects, leading to changes in the distribution of reaction products and different degradation pathways.
