Synthesis and Characterization of Novel MXeneCeria Heterostructure by Integration of Ti3C2Tx Quantum Dots into Fluorescent Nano-octahedral CeO2

Herein, we report the synthesis of a new stable zero/one-dimensional composite heterostructure “MXeneCeria” by integrating titanium carbide MXene (Ti3C2Tx) nanosheets-derived quantum dots with nano-octahedral particles of ceria (CeO2). This unique assimilation resulted in the formation of an auto-fluorescent aqueous colloidal material, which is detectable in fluorescent colors across various wavelengths, ranging from blue to green and red. The unique physicochemical properties of MXeneCeria make it a very promising nanocomposite and it may open a gateway to its potential applications in the biomedical field including tracking, immunoengineering, cell therapy, and targeted drug delivery.
