Nitrogen containing carbon nanotubes as supports for Pt – Alternate anodes for fuel cell applications

Aligned nitrogen containing carbon nanotubes have been synthesized using Anodisc alumina membrane as template. Highly dispersed<br>platinum nanoparticles have been supported on the nitrogen containing carbon nanotubes. Nitrogen containing carbon<br>nanotubes as platinum catalyst supports were characterized by electron microscopic technique and electrochemical analysis. The<br>EDX patterns show the presence of Pt and the micrograph of TEM shows that the Pt particles are uniformly distributed on the<br>surface of the nitrogen containing carbon nanotube with an average particle size of 3 nm. Cyclic voltammetry studies revealed a<br>higher catalytic activity of the nitrogen containing carbon nanotube supported Pt catalysts.
