Fluorinated Nanomaterials for Energy and Healthcare Applications View Presentation

Fluorine chemistry has gained tremendous attention in energy and sensing devices such as energy storage devices, hydrogen generation, solar cells, and gas sensors. Fluorination of nanomaterials (metal oxide nanoparticles and carbon-based nanomaterials) can significantly change their physical, chemical, and electrochemical properties. The conventional methods known for fluorination are not easily adaptable to various synthetic methods due to safety issues associated with the precursors. With the advent of commercially available electrophilic fluorinating precursors such as Selectfluor^TM (F-TEDA), it is interesting to synthesize fluorine functionalized nanomaterials by using them as a direct source of fluorine in solution. Many nanostructured materials such as Fe₂O₃, SnO₂, and nanocarbon are fluorinated for application as electrodes in supercapacitors, photoelectrochemical cells, and chemical sensors for enhanced charge transport and high performance of these devices, which will be presented briefly.
