Direct catalytic decomposition of ozone emerges as an effective method for ozone removal. Field experiments were conducted to evaluate the effectiveness of exterior wall coatings with ozone decomposition catalysts for ozone removal in practical applications. ANSYS 2020R1 software was first used for simulation and analysis of ozone concentration and flow fields to investigate the decomposition boundary of these wall coatings. The results show that the exterior wall coatings with manganese-based catalysts can effectively reduce the ozone concentration near the wall coating. The ozone decomposition efficiency is negatively correlated with the distance from the coating and the decomposition boundary range is around 18 m. The decomposition boundary will increase with the increase of temperature, and decrease with the increase of the wind speed and the relative humidity. These results underscore the viability of using exterior wall coatings with catalysts for controlling ozone pollution in atmospheric environments. This approach presents a promising avenue for addressing ozone pollution through self-purifying materials on building external wall.</div></div>","PeriodicalId":15788,"journal":{"name":"Journal of Environmental Sciences-china","volume":"154 ","pages":"Pages 847-858"},"PeriodicalIF":5.9,"publicationDate":"2024-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143152842","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To further lower the cost of catalysts, single atom catalysts (SAC) have been fabricated and extensively studied for application in VOCs oxidation due to their 100 % atom-utilization efficiency and unique catalytic performance.

Our findings revealed that water quality degradation significantly reduces the α-diversity of bacterial communities in water samples, while sediment samples remain unaffected. Additionally, water quality deterioration increases the complexity of bacterial networks in water samples but reduces it in sediment samples.

Notably, the chemical weathering processes have significantly facilitated the enhancement of humic-like components in the river water. Besides, the groundwater DOM characteristics were predominantly influenced by the mobilization of sedimentary organic matter and the introduction of allochthonous DOM resulting from surface-water recharge. Interestingly, humic-like components facilitated As enrichment through complexation and competitive adsorption effects in both surface water and groundwater under oxidizing conditions, which was supported by the significant positive correlations between As and humic-like component (<em>R</em><sup>2</sup> = 0.31/0.65, <em>P</em> &lt; 0.05/0.01) and the concurrent mobilization of As and humic-like components from sediment incubation experiments. Moreover, the Structural Equation Modeling analysis revealed a stronger contribution of humic-like components to the As enrichment in the groundwater compared with surface water, possibly due to the relatively stronger microbial activity and enhanced mobilization of humic-like components in alluvial aquifers.
