Description

• General description: Potassium fluoride is a white crystalline solid that is highly soluble in water. It is a strong base widely used in the field of catalysis, polymer synthesis, and semiconductor devices. [1] [2] KF has a relatively high melting point. It dissolves well in hydrofluoric acid. However, KF is insoluble in alcohol.
• Application: Potassium fluoride can be used:To fabricate CIGS thin films solar cells. Efficiency increased by up to 21.7% after KF postdeposition treatment. This was due to the formation of a K-containing layer on the CIGS surface, which resulted in increased surface reactivity due to the formation of a bilayer structure in which a K—In—Se species covers the CIGSe compound.[3]To fabricate 2D vanadium carbide MXene for supercapacitor electrodes.[4]To synthesize sulfonyl fluoride through electrochemical oxidative coupling.[5]As an electrolyte additive for Li-ion batteries.[6]As a catalyst for ring-opening fluorination of cyclic thioethers.[1]To synthesize solid base catalysts, KF/Ca−Mg−Al hydrotalcite for the production of Biodiesel via transesterification reactions.[2]
