Synthesis, Characterization and Catalytic Activity of Polyethylene Glycol (PEG) Functionalized MXene (Ti3C2Tx) for Methylene Blue Dye Degradation Under UV Light Irradiation

The emerging field of two-dimensional (2D) transition metal carbides and nitrides, collectively known as MXene (Ti ₃ C ₃ Tx), has garnered significant attention in recent years due to their remarkable properties and multifaceted applications. This work explores the synthesis, characterization and functionalization of MXene with polyethylene glycol (PEG) and its influence on the degradation process of organic dye methylene blue (MB) is investigated. The functionalization of MXene with PEG is detailed, showcasing the diverse chemistries and functionalities these organic compounds bring to the MXene nanosheets. PEG imparts hydrophilicity and stability, and promotes catalytic activity. Further the mechanisms of dye degradation involving MXene-PEG materials are elucidated, highlighting the synergistic effects of MXene and functional groups on the enhanced degradation rates. This work underscores the versatility of MXene as a platform for environmental applications and the significant impact of functionalization with organic molecules on their performance. The findings of this work revealed that when MXene-based nanomaterials suitably functionalized with PEG, they exhibit immense potential in the reduction of methylene blue (MB) dye with a record breaking first order rate constant of 0.16581 ± 0.030 min ^− 1 .
