MXene-based materials for enhanced water quality: Advances in remediation strategies

Ecotoxicology and Environmental Safety, Journal Year: 2025, Volume and Issue: 291, P. 117817 - 117817

Published: Feb. 1, 2025

Two-dimensional MXenes are promising candidates for water treatment because of their large surface area (e.g., exceeding 1000 m²/g certain structures), high electrical conductivity >1000 S/m), hydrophilicity, and chemical stability. Their strong sorption selectivity effective reduction capacity, exemplified by heavy metal adsorption efficiencies 95 % in several studies, coupled with facile modification, make them suitable removing diverse contaminants. Applications include the removal metals achieving >90 Pb(II)), dye demonstrating >80 methylene blue), radioactive waste elimination. Furthermore, 3D MXene architecture exhibit enhanced performance antibacterial activities against bacteria), desalination rejection percentage, photocatalytic degradation organic However, challenges have remained, which necessitate further investigation into toxicity assessing effects on aquatic organisms), scalability, cost-effectiveness large-scale production. This review summarizes recent advancements MXene-based functional materials wastewater remediation, critically analyzing both potential limitations.

K₂Cu₃(Fe(CN)₆)₂ In Situ-Modified MXene Nanosheets for Selective Enrichment of Cs⁺ and the Mechanism

Inorganic Chemistry, Journal Year: 2025, Volume and Issue: 64(10), P. 4920 - 4933

Published: March 5, 2025

Selective enrichment of cesium ions (Cs+) at ultralow concentrations is essential for resource recovery and radioactive waste disposal, yet efficient adsorbents are lacking. Herein, we reported a Prussian blue analogue (K2Cu3(Fe(CN)6)2, Cu-PBA) decorated on MXene nanosheets by in situ fabrication, forming composite material termed PMX, enhanced adsorption Cs+ acidic solutions seawater. The stable, negatively charged effectively anchors Cu2+ precursors promotes adsorption. synergistic interaction between the situ-synthesized Cu-PBA significantly enhances performance water stability PMX both achieves rapid equilibrium within 5 min, with high capacity 408.2 mg/g pH 1, surpassing conventional adsorbents. Moreover, shows excellent selectivity (Kd = 68,361.7 mL/g), cycle stability, notable anti-irradiation ability, demonstrating superior efficiency from complex matrices. mechanism involves electrostatic attraction K+/Cs+ ion exchange, facilitated MXene's functional groups structure. These findings underscore potential as an adsorbent removal elements such Cs+.

Nanohybrid of Silver‐MXene: A Promising Sorbent for Iodine Gas Capture from Nuclear Waste

Advanced Materials Interfaces, Journal Year: 2025, Volume and Issue: unknown

Published: April 4, 2025

Abstract The increasing reliance on nuclear energy as a significant low‐carbon power source necessitates effective solutions for managing radioactive emissions. This study introduces novel application of MXene nanohybrids, specifically silver‐MXene (Ag‐Ti 3 C 2 T x ), an sorbent radioiodine off‐gas capture at operating temperature 150 °C. Through comprehensive material characterization, including X‐ray diffraction, scanning and transmission electron microscopies, energy‐dispersive spectroscopy, Raman thermogravimetric analysis, inductively coupled plasma optical emission gas sorption analyses, the successful loading Ag nanoparticles onto Ti is confirmed subsequent formation AgI upon iodine capture. results demonstrate that Ag‐Ti exhibits superior uptake compared to traditional silver‐based sorbents such silver mordenite zeolite (AgZ) silver‐functionalized silica aerogel (AgAero). achieves 946 mg g −1 , significantly outperforming AgZ (131 ). These findings highlight potential highly efficient, thermally stable capture, potentially addressing key limitations existing materials.
