Implication
Methodological guide details optimal etching and delamination protocols for titanium carbide MXenes, establishing standardized practices to control flake quality across scalable applications.
Key Points
- Provide standardized experimental protocols and best practices for the selective chemical etching and delamination of two-dimensional titanium carbide (Ti3C2Tx) MXenes.
- Evaluated diverse selective chemical etching protocols using different etchants to selectively remove atomic layers from parent MAX phase precursors.
- Tested various delamination methods to isolate single- to few-layer 2D flakes in colloidal solution.
- Identified critical synthesis parameters, including etchant selection and reaction duration, that directly control the yield, flake size, and defect density of Ti3C2Tx.
- Established tailored processing workflows to maximize material quality and scalability for specific target uses, including energy storage, water purification, and electronics.
