Abstract

In this paper,the electrochemical reduction of benzaldehyde was investigated in C₄MIMBF₄、C₆MIMBF₄ and C₈MIMBF₄ ionic liquids by cyclic linear sweep voltammetry,cyclic square-wave voltammetry and chronocoulometry.Benzaldehyde exhibits two successive one-electron irreversible reduction(E_P1=-1.39 V,E_P2=1.69 V) with GC electrode in C₄MIMBF₄,the voltammetric data for benzaldehyde give diffusion coefficients of 1.5*10^-8cm²/s and 1.3*10⁸cm²/s.There is one current peak in C₆MIMBF₄ and C₈MIMBF₄ ionic liquids due to their stronger alkalinity then C₄MIMBF₄.The decay time of the charging current became longer in C₄MIMBF₄、C₆MIMBF₄、C₈MIMBF₄ ,and slower heterogeneous kinetics in C₆MIMBF₄ and C₈MIMBF₄ ionic liquids.
