Merck, 338869-25G, Ammonium fluoride

General description
Ammonium fluoride is a white crystalline solid soluble in water. It adopts the wurtzite crystal structure and forms mixed crystals similar to ice. It is also known for its use as an energetic fluorinating agent and finds application in the field of solar cells and batteries.
Application
Ammonium fluoride can be used:
To modify the interface between the electron transport layer and the perovskite layer of solar cells. This helps to reduce interfacial defects and charge recombination enhancing power conversion efficiency of perovskite solar cells (PSCs).
As a structure directing agent to prepare electroactive materials for supercapacitors.
To synthesize NiF₂/porous carbon (NPC) nanocomposite by a bottom-up method for cathodes of Li-ion battery. Heat treatment with NH₄F produces a high yield of metal fluoride/porous carbon nanocomposites.
