Enhanced titanium carbide MXene structure with CuO quantum dots as an electrode for advanced supercapacitor applications

Ti 3 C 2 : CuO quantum dot composites with different mass ratios (1 : 0.5, 1 : 1 and 1 : 2) were successfully synthesized through hydrofluoric acid etching of Ti 3 AlC 2 to obtain Ti 3 C 2 MXene, followed by sonication-assisted intercalation of quantum dots.
