Controllable synthesis of titanium nitride nanotubes by coaxial electrospinning and their application as a durable support for oxygen reduction reaction electrocatalysts

Abstract

Chemical and electrochemical corrosion of a support limits the corresponding catalyst's performance and lifetime. In this paper, uniform TiN nanotubes are synthesized via coaxial-electrospinning, thermal oxidation and nitridation. The average diameter of nanotubes can be facilely controlled by tuning the parameters of coaxial electrospinning. The TiN nanotubes are modified further with Pt nanoparticles as Pt/TiN NT electrocatalysts. After accelerated durability tests, the electrochemical surface area (ECSA) and mass activity of the Pt/TiN decrease by only 6% and 14% respectively, while those of the Pt/C decrease by 44% and 46.2% respectively. The enhanced activity is attributed to the strong interaction between the Pt nanoparticles and the TiN support, which is confirmed by the X-ray dispersive spectra of Pt 4f.
