The electrochemical behavior of nitromethane were studied by cyclic vohammetry and in situ FTIR technique in the room temperature ionic liquid 1-butyl-3-methylimidazolium tetrafluorobrate( BMImBF_4 ) on a copper disk electrode. The influences of temperature and scan rate on the electrochemical characteristics of nitromethane were also investigated. Results show that the electroreduction of nitromethane in BMImBF_4 is an irreversible process, which is controlled by diffusion. Finally nitromethane is reduced into trans-dimer of nitrosomethane in BMImBF_4.
