英文摘要：

The electrochemical behavior of m-nitrobenzoic acid（mNBA）on the Cu electrode in ionic liquid 1-methylimidazolium trifluoroactate（HMimCF3COO） was investigated by cyclic voltammetry, linear scan method, chronoamperometry and chronocoulometry. The diffusion coefficient D of mNBA in HMimCF3COO was 1. 104× 10^-6 cm^2/s. It can be proved that the reduction of mNBA on Cu electrode was an irreversible process and the electrode process was controlled by diffusion. The apparent active energy of the electrode process was 38.5 kJ/mol, and that of the electrochemical step was 20.6 kJ/mol.
