Abstract

We investigated the influence of nitrogen doping on the electrocatalytic effect of TiO2 nanofibers by electrochemical methods. The electrocatalytic activities of nitrogen-doped TiO2 nanofibers (N-TiO2) produced using urea as the source of nitrogen and undoped TiO2 nanofibers were compared. The results showed that the N-TiO2 nanofibers possessed high activity in electrocatalytic oxidation of hydroquinone in buffer solution. The N-TiO2 nanofibers exhibited excellent catalytic activity because nitrogen doping changed the morphology of the nanofibers. Thus, nitrogen doping is a promising approach to enhance the electrocatalytic activity of TiO2 nanofibers in hydroquinone oxidation.
