Electrochemical Reduction of Nitrobenzene on the WC Electrode in Acidic Solution

MA Chun-an~(*),CHU You-qun,ZHU Ying-hong,XU Zhi-hua (Department of Applied Chemistry, Zhejiang University of Technology, Hangzhou 310032,China)  
The tungsten carbide (WC) electrode was constructed by using polyterafluoroethylene as binder. The electrochemical behavior of nitrobenzene on the WC electrode in acidic solution was investigated by cyclic voltammetry, linear scan method and chronoamperometry. Experimental results showed that WC electrode had good activity for the electrochemical reduction of nitrobenzene, and the electrode process was controlled by diffusion and electrochemical stepssimultaneously. The apparent active energy of the electrode process is 23.7kJ mol~(-1), while the active energy of the electrochemicalstep is 10.91kJ mol~(-1).
