Summary: In this study, high-mobility lattice oxygen-rich MnOOH nanorods were successfully synthesized and used to inhibit bromate formation during catalytic ozonation in wastewater treatment. The MnOOH nanorods exhibited excellent performance in bromate control and simultaneous degradation of 4-nitrophenol. The effective decomposition of ozone and reduction of bromate into bromide by lattice oxygen-rich MnOOH were the key mechanisms contributing to the inhibition of bromate formation.

Summary: We investigated the catalytic activity of magnetic CeZrUiO-66 Metal-Organic Framework (MOF) composites (Fe3O4/CeZrUiO-66) for ciprofloxacin degradation by catalytic ozonation. The composite with a 30:70 ratio of Fe3O4:CeZrUiO-66 exhibited the highest efficiency, achieving a 97% elimination yield within 30 minutes. The catalytic ozonation process (COP) showed higher CIP mineralization compared to the single ozonation process (SOP), and OH radicals were identified as the main reactive species.

Summary: A catalyst GQDs@MnOOH was synthesized to enhance the catalytic ozonation of the antibiotic ciprofloxacin (CIP). The GQDs@MnOOH/O3 system showed the highest CIP removal effectiveness compared to MnOOH/O3 and O3 only. The degradation of 0.02 mM CIP reached 99.9% efficiency in 30 min using 9.6 mg L-1 of O3 catalyzed by 12.5 mg L-1 of GQDs@MnOOH. The GQDs@MnOOH enhanced CIP degradation and inhibited the formation of BrO3- in different water sources. Oxygen radical (O2 center dot-), singlet oxygen (1O2), and hydroxyl radicals (center dot OH) were involved in CIP degradation by the GQDs@MnOOH/O3 system.

Summary: Disinfection in water treatment systems helps eliminate health risks, but can also produce harmful disinfection by-products. Formation of potentially carcinogenic bromate during ozonation of bromide-containing waters has led to investigations into physical/chemical or biological reduction methods to mitigate the issue. Adsorption-based physical methods have been found to be more effective than chemical methods in potable water treatment.

Summary: This study demonstrates the efficient removal of chlorinated volatile organic compounds (CVOCs) and high selectivity for CO2 by utilizing dodecylamine-modified Co3O4 catalysts. The optimized surface structure of the catalyst greatly enhances the cleavage of the C-Cl bond at low temperatures. Photocatalysis plays a crucial role in the oxidation of intermediates during dichlorination, leading to a significant improvement in CO2 selectivity. The synergistic effect between ozone and light is confirmed to enhance the performance of the catalyst.

Summary: This study assessed and compared the efficiencies of ozonation and ozone with hydrogen peroxide for the removal of organic micropollutants (OMPs), as well as the inactivation of bacteria and viruses, and the formation of bromate and biodegradable organics in municipal wastewater effluent. The results showed that ozonation effectively eliminated 39 OMPs, with 22 OMPs achieving a removal rate of 54 ± 14% at an ozone dosage of 0.5 gO(3)/gDOC. The concentration and exposure time of ozone were positively correlated with microbial inactivation levels, and O-3/H2O2 minimized bromate formation but decreased bacteria/virus inactivation. Ozonation also produced biodegradable organics, which could be removed through post-biodegradation treatment.

Summary: The trade-off between micropollutant abatement and bromate formation is inevitable during the ozonation of bromide-containing water. To overcome this compromise, a novel adsorption enhanced membrane contact ozonation (AEMCO) process was developed, which accelerated the oxidation of micropollutants and reduced the formation of bromate. In the AEMCO process, the removal efficiency of ciprofloxacin was 97.15% while the yield of bromate was 0.7 μg/L, compared to 39.96% and 8.3 μg/L in the conventional MCO process. Additionally, a reformative Hatta number (Ha-CIP) was used to evaluate the relationship between interface adsorption and chemical reactions, guiding the adjustment of operating parameters. These findings provide a potent strategy to balance micropollutant abatement and bromate formation during the ozonation process.

Summary: Transition metal oxides and transition metal containing oxides have been extensively researched in heterogeneous catalytic ozonation for water treatment. The catalytic mechanism for typical transition metal oxide - manganese oxide (MnO2) in catalytic ozonation remains unclear. The study found that electron transfer reaction occurs in manganese containing oxides catalytic ozonation when ozone is adsorbed on protonated surface hydroxyl groups of acid sites, but not in magnesium manganese oxides (MgMnxOy). The protonation ability of hydroxyl groups on acid sites and electron transfer ability of acid sites are positively related to Mg content in MgMnxOy.

Summary: Ozone is widely used in drinking water as a disinfectant and oxidant, and has recently been applied in municipal wastewater treatment for potable reuse and ecosystem protection. However, the formation of bromate during ozonation, which is a potential human carcinogen, poses a challenge. The mechanisms of bromate formation from bromide are complex and involve reactions with both ozone and secondary oxidants. Various strategies can be applied, such as controlling bromide discharge, minimizing bromate formation during ozonation through chemical control, implementing pretreatment strategies, and utilizing downstream treatment processes for bromate abatement.

Summary: Doping of F into g-C3N4 (CN) effectively regulated N vacancies, hydrophobic sites, and electron rich zone, leading to enhanced photocatalytic ozonation of PFOA. F-CN exhibited superior activity compared to CN, achieving 74.3% PFOA removal in F-CN/Vis/O3 compared to only 57.1% in CN/Vis/O3. The presence of N vacancies played a vital role in the oxidation of PFOA through photogenerated hole (hvb+) oxidation. The hydrophobic sites facilitated mass transfer and enhanced the generation of hydroxyl radicals (center dot OH) through O3's single electron reduction, while reducing the recombination of hvb+-ecb-. The degradation of PFOA in F-CN/Vis/O3 involved the gradual shortening of perfluoroalkyl chain and loss of the CF2 unit.

The novel hybrid photocatalyst TiO2/C/SiO2 exhibited well-coupled adsorption and visible light photocatalysis on chlorpromazine (CPZ). O-2(-) free radicals were identified as the main reactive species for CPZ degradation, and the enhanced performance of the photocatalyst could be attributed to increased adsorption and high exposure of the TiO2 QDs surface.

The modified catalyst shows enhanced activity and stability due to increased acid sites and hydrophobicity. The catalyst exhibits superior IBP and TOC removal compared to sole O3 and Fe-MCM-41 processes. The presence of certain ions and high concentration humic acid can either hinder or promote the IBP degradation by the catalyst. The catalyst also performs well in different water matrices.
