Influence of Nitrogen Doping on the Electrocatalytic Effect of TiO2 Nanofibers

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 Tiv 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. (c) 2017 The Electrochemical Society. All rights reserved.
