This review critically examines the current status of MSWIBA management in China, including generation, physicochemical characteristics, and national regulatory frameworks.

AmMOFs usually combine the advantages of crystalline MOFs (CrMOFs) including high surface area, exceptional chemical and thermal stabilities, chemical functionalities, and tunable pore sizes/shapes, with the emerging properties of amorphous counterparts including the absence of grain boundaries, abundant defects and active sites, isotropy, high flexibility, and enhanced mechanical robustness. Although the number of reports on AmMOFs is much lower than those on CrMOFs, in some examples they exhibit improved properties and have also attracted increasing attention in the recent years, thereby they will possess great potential in the future technologies. This review aims to highlight the recent progress of AmMOFs in synthesis methods, structure-property relationships, and emerging applications. In this regard, we highlight the superiority of AmMFs compared to their crystalline counterparts, then describe two primary approaches for preparing AmMOFs including: 1) top-down: amorphization of pre-synthesized CrMOFs via different treatment methods, and 2) bottom-up: direct synthesis of AmMOFs. Additionally, we highlight the recent progress of AmMOFs in different fields including biomedical, catalysis/photocatalysis, energy storage and conversion, chemical sensing, gas adsorption and separation, and water/wastewater treatment applications.</div></div>","PeriodicalId":15759,"journal":{"name":"Journal of Environmental Chemical Engineering","volume":"13 5","pages":"Article 117890"},"PeriodicalIF":7.4,"publicationDate":"2025-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144595390","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}

The distinctive attributes of adsorption support its wide-scale application in the remediation of contaminants including PFASs. Previous studies mainly focused on the exploration and development of adsorbent materials, evaluating the removal of PFASs with different chain lengths, or assessing the impact of environmental factors on PFASs removal. However, the role of microbubbles (MBs) or nanobubbles (NBs), a commonly present but easily overlooked substance in natural media, in the PFASs adsorption has not been systematically summarized. Therefore, in this review, we introduce the importance of MBs/NBs in PFASs (particularly PFOA and PFOS) adsorption, by analyzing their characteristics related to adsorption. MBs/NBs can effectively remove PFASs by enriching at the interface and prolonging the retention time. The theoretical calculations of molecular dynamics and Gibbs free energy on the adsorption behavior of PFOS/PFOS with the participation of MBs/NBs were systematically analyzed. The hydrophobicity of PFOS, which is greater than that of PFOA, leads to stronger adsorption of PFOS by MBs. Environmental factors mainly affect the stability and surface properties of MBs/NBs, as well as the hydrophobicity of PFOA/PFOS, to alter the adsorption behavior of PFOA/PFOS mediated by MBs/NBs. Furthermore, the adsorption mechanisms of PFOA/PFOS on MBs/NBs were summarized, with electrostatic and hydrophobic interactions dominating this behavior. This review offers an enhanced and comprehensive insight into the adsorption of PFASs in water. Furthermore, it facilitates a more profound evaluation of the significant role played by MBs/NBs in the adsorptive elimination of PFASs from aquatic system.</div></div>","PeriodicalId":15759,"journal":{"name":"Journal of Environmental Chemical Engineering","volume":"13 5","pages":"Article 117832"},"PeriodicalIF":7.4,"publicationDate":"2025-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144549368","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}
