Nano zero-valent iron (nZVI) has emerged as a promising material for arsenic removal due to its high surface area, excellent reduction capacity, and unique core-shell structure. However, its practical application is hindered by inherent limitations such as particle agglomeration, surface passivation, and oxidative deactivation. This review systematically examines recent advances in nZVI and its composites for inorganic arsenic removal from wastewater. First, we summarize nZVI synthesis methods, including physical and chemical approaches, highlighting the potential of green in situ synthesis for sustainable groundwater remediation. Next, we critically analyze key modification strategies for nZVI, including bimetallic modification, sulfidation modification, surfactant modification, and solid-loading modification, and emphasize the shift from single modifications to synergistic multifunctional designs. Furthermore, we evaluate the influence of environmental factors, including pH, coexisting ions, adsorbent dosage, and reaction time, on arsenic removal efficiency. The underlying mechanisms—primarily adsorption, oxidation, and coprecipitation—are thoroughly discussed. Finally, we identify current challenges and future research directions for nZVI-based materials in global applications. This review provides valuable insights for designing eco-friendly, cost-effective, and high-performance arsenic removal technologies.</p></div>","PeriodicalId":605,"journal":{"name":"JOM","volume":"78 3","pages":"2242 - 2272"},"PeriodicalIF":2.3,"publicationDate":"2026-01-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147337292","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, the main objective of this article is to design a new pavement base composite material made of RM, SS, and cement. This material can reduce the amount of cement needed and enable the effective use of industrial solid waste, and it has been successfully applied to a road project. First, seven cement dosage gradients of 0%, 2%, 4%, 6%, 8%, 10% and 12% were established to investigate the mechanical properties of the composites with different SS and RM dosages. Second, the freeze-thaw and dry-shrinkage deformation resistance of the new material was evaluated by the freeze-thaw cycle test and dry-shrinkage test. Finally, via X-ray diffractometer, SEM, and energy spectrometer (EDS), the characteristics of the hydration reaction and the microscopic action mechanism were revealed. The results show that the mechanical properties of RM-SS-cement composites meet the requirements of roadbed surface layers. The main hydration products include CaCO<sub>3</sub>, C<sub>2</sub>S, AFt, C-S-H, Ca(OH)<sub>2</sub>, C-A-H, and Mg(OH)<sub>2</sub>, among others. Of these, the crystal strengths of Mg(OH)<sub>2</sub>, C-S-H, C-A-H, and AFt are higher, and the generation of AFt crystals is an important reason for the small shrinkage and deformation of the material. The addition of an appropriate amount of RM can enhance the hydration activity of SS. The Al and Si systems can effectively cement heavy metal ions, and the synergistic effect among RM, SS, and cement is good. Therefore, the RM-SS-cement composite developed in this article is a high-quality construction material for road engineering.</p></div>","PeriodicalId":605,"journal":{"name":"JOM","volume":"78 4","pages":"3264 - 3281"},"PeriodicalIF":2.3,"publicationDate":"2025-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147561998","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In full immersion, the total charge transfer resistance is nine times higher than pure zinc coatings, reflecting improved resistance to corrosive media.
