| Description |
The influence of surface characteristics of multi-walled carbon
nanotubes (MWNTs) support on the catalytic performance of
PEFC electrodes is investigated by using oxidized and nonoxidized
MWNTs as the supports for platinum. The defect-free
morphology, high electrical conductivity and favorable pore-size
distribution of non-oxidized MWNTs ameliorate catalytic activity
and electrochemical stability of platinum. Physico-chemical
properties of oxidized and non-oxidized MWNTs and the
respective catalysts are studied by BET surface-area, XRD, XPS
and TEM measurements. Electrochemical stability of MWNTssupported
platinum as PEFC electrodes is assessed using potential
cycling and potentiostatic techniques. Owing to the higher
corrosion-resistance, platinum on non-oxidized MWNTs show
lower loss in electrochemical surface area (ESA) and also exhibit
22% lower corrosion current than oxidized MWNTs.
