Paz. Suarez et al., ENLARGED ELECTROCHEMICAL WINDOW IN DIALKYL-IMIDAZOLIUM CATION BASED ROOM-TEMPERATURE AIR AND WATER-STABLE MOLTEN-SALTS, Electrochimica acta, 42(16), 1997, pp. 2533-2535
The electrochemical windows of the ionic liquids 1-n-butyl-3-methyl im
idazolium tetrafluoroborate (BMI+)(BF4-) and 1-butyl-3-methyl imidazol
ium hexafluorophosphate (BMI+)(PF6-) have been investigated at platinu
m, vitreous carbon, tungsten and gold electrodes. The lowest current d
ensities and widest electrochemical windows were found on tungsten and
vitreous carbon 6.10 and 5.45 V for (BMI+)(BF4-) and > 7.10 and 6.35
V for (BMI+)(PF6-), respectively. (C) 1997 Elsevier Science Ltd.
