This study innovatively combined immobilized enzyme MIL-88B (Fe)/HRP with three plant species to construct a novel air purification system. The aim is to enhance the purification rate of plants for benzene. By evaluating the purification effects of the combined system on benzene under different initial concentrations and exposure times, the study also analyzes the impact of immobilized enzymes on the antioxidant system of plants. The results indicate that after introducing MIL-88B (Fe)/HRP into the rhizosphere solution of plants, the transport rates of Spathiphyllum kochii, Epipremnum aureum, and Chlorophytum comosum in the combined system significantly increased, by 294, 418, and 334 times, respectively, compared to the single plant system. The maximum purification rates were 3.87, 3.18, and 1.42 times higher than the single systems. Immobilized enzymes increased the activity of POD enzymes in plants, enhancing plant tolerance to benzene. The effective degradation of benzene in the rhizosphere solution by MIL-88B (Fe)/HRP has led to the creation of a benzene concentration gradient across multiple interfaces of the air-leaf-root-rhizosphere solution, facilitating the unidirectional transport of benzene within the plant body. This process enhances the plant's purification ability towards benzene.

The rising emissions of gases, such as carbon dioxide (CO2), nitrogen oxide (NOx), and volatile organic compounds (VOCs) have become pressing environmental issues. Addressing the growing emission of CO2 and gaseous pollutants urgently requires the development of new materials that can enhance the efficiency of adsorption or catalysis systems. Mesoporous materials have attracted much attention for gases capture and conversion, due to their exceptionally high surface area, interconnect pore network, and superior mass transfer. These characteristics promise improvements in adsorption/catalysis capabilities, as well as in materials durability and stability. This review explores recent advancements in mesoporous materials, such as mesoporous metal oxides (e.g., mesoporous TiO2, MnO2, Co3O4, and CeO2), mesoporous silicas, and mesoporous carbon for the adsorption or catalysis of gaseous pollutants (i.e., CO2, NOx, and VOCs). Their mesoporous texture and surface chemistry, along with the influence of loading species (e.g., metal and metal oxides) on their efficiency and selectivity for gases capture and conversion, are detailed. Furthermore, the review outlines prevailing trends, identifies key challenges in the development of mesoporous materials, delineates future research directions, and proposes strategies to achieve the deployment of mesoporous materials in gas adsorption and catalysis.","PeriodicalId":73,"journal":{"name":"Environmental Science: Nano","volume":null,"pages":null},"PeriodicalIF":8.131,"publicationDate":"2024-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142231617","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}

About 98.5 % of 25 mg/L MTZ was effectively degraded with a catalyst dosage of 20 mg/50mL under 90 min of sunlight irradiation. Moreover, a total organic carbon (TOC) removal of 78.5 % was achieved within the same duration under optimal conditions. The simultaneous transfer of photogenerated electron-hole pairs in the two Z-scheme pathways described here can significantly accelerate the charge separation and enhance ROS production. The effect of catalyst dose, initial MTZ concentration, inorganic cations (Na+, Mg2+, Ca2+, and Al3+), inorganic anions (Cl-, CO32-, NO3-, and SO42-), organic compounds (SDS, urea, HA, and acetone), and different water matrices on the degradation of MTZ by FCM was analyzed systematically. Furthermore, comprehending the spatial separation and transfer of photogenerated charge carriers, as well as the formation of ROS at the heterojunction interface, is critical for understanding photocatalytic degradation mechanisms. Consequently, a plausible MTZ breakdown route and charge transfer pathway were established based on the radical scavenging experiments, ESR and LCMS analysis.
