摘要
The multi-wall carbon nanotubes（MWNTs）modified glassy carbon electrode（CNT/GCE）was fabricated and its electrocatalytic activity of hydroquinone was investigated.It was found that the electrochemical behaviors were greatly improved at CNT/GC,indicating that the redox of hydroquinone could be catalyzed at CNT/GC.The kinetic parameters of thisprocess were calculated.The diffusiong coefficient was 1.7×10-5cm2·s-1,the heterogeneouselectron transfer rate constant k was 0.678s-1,α value was 0.538 and electron transfer numbers was 2.

It was found that the electrochemical behaviors were greatly improved at CNT/ GC, indicating that the redox of hydroquinone could be catalyzed at CNT/GC. The kinetic parameters of thisproeess were calculated. The diffusiong coefficient was 1.7 × 10^-5cm^2 ·s^-1 ,the heterogeneouselectron transfer rate constant k was 0.678s^-1 ,α value was 0.538 and electron transfer numbers was 2.
