%X The film contained L-cysteine and gold nanoparticles were provided by self-assembled monolayers (SAMs) and potentiostatic electrodeposition technology on the gold electrode. Two methods were used to study the film: In the first, cyclic voltammetry (CV) was used to inspect the functional groups of the film and the same time hydroquinone was chosen to be a probe molecule in the based solution; secondly, based on analytical technology of scanning electrochemical microscopy (SECM), the heterogeneous rate constant (k<sub>eff</sub>) between solid phase (the modified electrode) and liquid phase (K<sub>3</sub>Fe(CN)<sub>6</sub>) was obtained. As a result, the better binary catalysis of hydroquinone was demonstrated and the heterogeneous rate constant (k<sub>eff</sub>) is the greater at 8 h for L-cysteine self-assembled monolayers (SAMs).
