Nanoscale Zero-Valent Iron and Electrochemical Remediation of Chlorinated Contaminants
This community develops chemical and electrochemical methods to remove chlorinated organic pollutants and heavy metals from water and soil, primarily using nanoscale zero-valent iron and catalytic surfaces.
The research focuses on the synthesis and application of nanoscale zero-valent iron (nZVI) and its composites with activated carbon, graphene oxide, and biochar. Key mechanisms include reductive dechlorination, hydrodechlorination, and electron transfer processes that degrade polychlorinated biphenyls, chlorophenols, and hexavalent chromium. The work also examines isotope fractionation to track reaction pathways and the use of permeable reactive barriers for in-situ groundwater treatment. Recent studies explore electrocatalytic systems using single-atom catalysts for efficient dechlorination and the immobilization of heavy metals like cadmium in contaminated soils.
The largest share of the community's output is found in iron research, accounting for 60.0% of all iron research tracked, and 2,513 papers here. Chlorine research follows with 80.0% of all chlorine research tracked, and 2,058 papers here.
The community comprises 7,682 papers, publishing most frequently in Environmental Science & Technology, Journal of Hazardous Materials, and Chemosphere.
The newest papers describe electrochemical dechlorination strategies, the influence of humic acid on nZVI stability in groundwater, and the use of cob(II)alamin with zero-valent iron for selective pollutant removal.
