✦ Synopsis

The electrochemical windows of the ionic liquids I-n-butyl-3-methyl imidazolium tetrafluoroborate (BMI+)(BF;) and I-butyl-3-methyl imidazolium hexafluorophosphate (BMI+)(PF;) have been investigated at platinum, vitreous carbon, tungsten and gold electrodes. The lowest current densities and widest electrochemical windows were found on tungsten and vitreous carbon 6.10 and 5.45 V for (BMI + )(BF; ) and >7.10 and 6.35 V for (BMI+)(PF;), respectively.
