- Description
- Pt-Ru-P was prepared by the chemical reduction
method using sodium hypophoshite as a reducing agent on Vulcan XC
72 and multi-walled carbon nano-tubes (MWCNTs). Sodium citrate was
added as the stabilizer during electro-catalyst preparation. The
electro-catalytic activity towards methanol oxidation in acidic
medium was studied by cyclic voltammetry and linear sweep
voltammetry. Pt-Ru-P/MWCNT showed excellent activity compared to
that of Pt-Ru-P/C. This may be attributed to the effectiveness of
the MWCNTs acting as good catalyst support material. The particle
size of both electro-catalysts obtained with the transmission
scanning electron microscopy (TEM) ranged between 2-4nm desirable
for the direct methanol fuel cells.
