Abstract: The structure and morphology of carbon nanotubes modified by high-temperature calcination and miling with high speed were studied. The surface area of carbon nanotubes was measured. The morphology of the carbon nanotubes electrocatalytic electrodes pressed at noal temperature was observed. Active red X-3B simulated wastewater was disposed by active carbon, graphite and carbon nanotubes electrocatalytic electrodes, respectively. The experimental results show that the stability of carbon nanotubes electrodes is good and the dye degradation of X-3B can reach
96.55%. The efficiency of carbon nanotubes electrodes is obviously better than that of active carbon and graphite electrodes.
