Abstract
Section titled âAbstractâThe first successful electrosynthesis of polycrystalline Ag II FBF 4 and single crystalline Ag II F 2 in both galvanostatic and potentiostatic conditions was achieved at the BoronâDoped Diamond electrode in anhydrous hydrogen fluoride. Silver(I) oxidation and the F 2 evolution reactions are well separated in the potential scale. Temperature of performing electrosynthesis as well as BF 3 overpressure were found to be key variables of the process. Impedance spectroscopy measurements provided insight into the mechanism of formation of silver(II) fluorides pointing out to the presence of HFâsoluble Ag(BF 4 ) 2 intermediate. The phase purity of the products was determined by Xâray diffraction.
