- Abstract
The method was utilized to optimize the nitrogen-doped conditions of plasma nitrogen-response surface doped Ti02 nanotubes ( N-Ti02 ) to fabricate catalysts with high photoelectrocatalytic activity, which was measured by the photoelectrocatalytic decolorization of reactive brilliant red K-2BP. The effects of nitrogen-doped power time and bias voltage were studied in single factor experiments. Based on the results, a response surface model including three factors was established in Design-Expert 8. 0,which could perform AN0V0,contour and 3D curve analysis. The results show that the photocatalytic activity of N-Ti02 nanotubes was the best when the nitrogen-doped power,time and bias voltage were 10 W,90 s, 20 V. It was proved that the error rate between the modeled and observed values of the response target model was only 0.79%,the band gap of N-Ti02 nanotubes was significantly reduced.
