摘要

The present work primarily aims to evaluate the adsorption properties of MXene and its nanocomposite, Fe3O4@MXene, for removing heavy metal ions from industrial wastewater. Two-dimensional (2D) MXene nanosheets were combined with Fe3O4 nanoparticles through a hydrothermal synthesis process to create the Fe3O4@MXene nanocomposite. Characterization revealed that Fe3O4 nanoparticles self-assembled onto MXene sheets, forming a structure that enhanced the 2D structure of MXene, with nanoparticles uniformly distributed throughout the nanosheet network. Performance experiments demonstrated that Fe3O4@MXene nanocomposite significantly outperformed pristine MXene in adsorbing heavy metal ions from wastewater. Notably, Fe3O4@MXene nanocomposite achieved an 83% removal efficiency for Cu ions, highlighting its potential as a highly efficient adsorbent in industrial wastewater treatment. This work underscores the viability of Fe3O4@MXene for heavy metal remediation, marking an important step toward practical environmental applications of MXene-based materials.
