Abstract:
Electrochemical behaviors of the bis(trifluoromethylsulfonyl)imide ([TFSI] − )-based ionic liquids consisting of 1-butyl-3-methylpyrrolidinium ([Py 1,4 ] + ), methyltributylammonium ([N 1,4,4,4 ] + ), and methyltrioctylammonium ([N 1,8,8,8 ] + ) cations were investigated by using low-index Au single crystal electrodes by cyclic voltammetry. The voltammetric feature was dependent on both the structure of the cation and the crystallographic orientation of Au. The electrochemical potential window of the [TFSI] − -based ILs was found to be only dependent upon the chemical structure of the cation. For each Au crystal plane, the electrochemical potential window of each IL was roughly estimated to be approximately 5.5 V, 5.6 V, and 5.8 V for [Py 1,4 ][TFSI] , [N 1,4,4,4 ][TFSI] and [N 1,8,8,8 ][TFSI] , respectively.
