Abstract

Multi Wall Carbon Nanotubes (MWCNT) are used as catalyst support due to their properties such as thermal stability and electron conduction among others [1]. In the last few years, MWCNT have been synthesized using a wide variety of methods; one of them is spray pyrolysis [2]; it presents advantages over other methods, i.e. easiness to control operating conditions and scalability. It had been demonstrated that CNT are obtained using organometallic compounds as catalytic agents [3,4]. This work proposes nickelocene as catalytic agent to grow MWCNT and its use to support metallic nanoparticles. Pt-Ru precursors were deposited on MWCNT using an aqueous deposition method assisted by ultrasound. Electrocatalysts were characterized by SEM-EDS and TEM. MWCNT shows length of 30 microns and diameter between 50 and 70 nm. Pt, Ru and Ni particles obtained are in nanometric scale. Synthesized nanostructured material could be considered as a good candidate for catalyst in PEM or Methanol fuel cells [5].
