Nanostructured encapsulation using nanomaterials, such as carbon nanotubes, metal-organic frameworks (MOFs), graphene oxide, and bio-inspired designs has shown potential in stabilizing CO₂ within solid matrices, enabling controlled hydrate formation and storage. However, fluctuating pressure, temperature, and salinity conditions, especially in harsh environments, challenge encapsulation stability, requiring material optimization for sediment compatibility. Nanomaterials additives enhance hydrate stability, CO₂ absorption efficiency, and mass transfer, though the performance depends on type, size, texture, composition, and formation conditions. Synergistic effects between nanomaterials and surfactants/polymers further improve interfacial tension (IFT) reduction, induction time, and storage capacity. This work highlights key mechanisms governing nanomaterials' CO₂ uptake in subseafloor sediments, including adsorption/absorption, diffusion, structural modifications, confinement effects, and hydrophobic interactions. In addition, the study underscores advanced characterization techniques, such as Raman spectroscopy, XRD, and molecular dynamics, providing insights into structural and thermal properties, while field studies in regions like the North Sea and Norway highlight practical challenges. Despite progress, scalability, cost-effectiveness, and environmental safety under variable subsea conditions remain hurdles. Emerging innovations, such as stimuli-responsive nanomaterials and hierarchical encapsulation architectures, could optimize long-term CO₂ storage and controlled release. By integrating the collective findings drawn from both empirical data in published papers and theoretical deductions, this work provides a roadmap to enhance comprehension regarding the screening, design, formation, nucleation, and growth of CO₂ hydrate in nanostructured encapsulation system toward sustainable CO₂ storage and global decarbonization goals.</div></div>","PeriodicalId":15759,"journal":{"name":"Journal of Environmental Chemical Engineering","volume":"13 5","pages":"Article 117765"},"PeriodicalIF":7.4,"publicationDate":"2025-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144502740","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although ozonation-assisted electrocoagulation (ECO) research has attracted growing attention, there is currently a lack of systematic summary to bridge the gap between lab-scale studies and pilot-scale applications. Therefore, we summarize existing findings on ECO, clarify current challenges and propose future research directions. This review outlines the progress and practical applications of ECO, covering synergistic contaminant removal mechanisms, electrode and reactor design, life cycle assessment and contaminant elimination. The innovative contribution of this review is that it is the first to systematically summarize the research on ECO, providing theoretical guidance for transitioning ECO from the laboratory scale to practical applications. In summary, the maximum synergistic coefficient between electrocoagulation (EC) and ozonation reaches 19.09, depending on the interaction between EC-generated flocs and ozone. Such a high synergistic coefficient demonstrates that the ECO is worthy of in-depth research. ECO can achieve approximately 100 % removal efficiency for SS, over 80 % removal efficiency for COD and ROCs, as well as partial removal of heavy metals. Notably, the energy consumption of the ECO ranges from 3.77 to 47.65 kWh/m³ , which is significantly lower than that of other EC-related processes, proving ECO feasibility for pilot-scale treatment. In the future, ECO research should be focused on the synergistic reaction mechanism, sludge resource utilization, design and optimization of scaling-up reactors, renewable energy integration and multi-technology coupling to advance practical applications.</div></div>","PeriodicalId":15759,"journal":{"name":"Journal of Environmental Chemical Engineering","volume":"13 5","pages":"Article 117685"},"PeriodicalIF":7.4,"publicationDate":"2025-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144502807","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These chemicals contaminate drinking water and irrigation systems, including surface and groundwater supplies. Despite ongoing efforts to regulate and restrict PFAS, these substances remain widely used, with new variants still being developed. Various treatment processes have been explored to address this issue, with hydrogel-based adsorption emerging as a promising approach. This review evaluates the role of hydrogels and their composites in remediating PFAS-contaminated water. Advanced treatment methods, including oxidation, coagulation, and adsorption with conventional adsorbents, are compared to hydrogel-based adsorbents. Hydrogels offer advantages such as enhanced recovery, reusability, and the ability to concentrate PFAS for subsequent degradation via oxidative methods. Furthermore, their tunable hydrophilic and hydrophobic properties enable efficient removal of both long- and short-chain PFAS. The highest PFAS removal efficiencies, exceeding 90%, and adsorption capacities of up to 1276<!--> <!-->mg/g have been reported for hydrogels containing cationic or quaternary ammonium groups. Theoretical studies suggest that hydrophobic interactions play a dominant role in the removal of long-chain PFAS, such as perfluorooctanoic acid (PFOA).

By highlighting the benefits and limitations of hydrogels, this review underscores their potential as versatile tools for addressing the global challenge of PFAS contamination.
