Fluorination of antimonene hexagons

Area of Science:

• Materials Science
• Nanotechnology
• Surface Chemistry

Background:

• Two-dimensional (2D) materials offer unique electronic and physical properties.
• Antimonene, a heavy 2D pnictogen, shows promise for novel applications.
• Controlled surface functionalization is key to tailoring material properties.

Purpose of the Study:

• To investigate the fluorination of 2D antimonene synthesized via a colloidal bottom-up approach.
• To explore the efficacy of microwave-induced plasma and reactive ion etching for antimonene fluorination.
• To confirm the stability of the resulting fluorine-antimonene bonds.

Main Methods:

• Synthesis of 2D antimonene using a colloidal bottom-up method.
• Fluorination using microwave-induced plasma with CF₄.
• Fluorination using reactive ion etching with CF₄.
• Density Functional Theory (DFT) calculations to assess bond stability.

Main Results:

• Successful fluorination of 2D antimonene hexagons was achieved.
• Both microwave-induced plasma and reactive ion etching proved effective fluorination strategies.
• DFT calculations corroborated the stability of the fluorine-antimonene bonds.

Conclusions:

• Fluorination of 2D antimonene is feasible using established plasma and etching techniques.
• The generated fluorine bonds on antimonene are stable.
• This research opens avenues for creating novel halogen-derivative 2D pnictogen materials.
