C

arbon nanotubes (CNTs) have attracted great interest as

catalyst supports due to their unique properties, including

excellent electronic conductivity, large surface area and high

chemical stability. However, pristine CNTs are chemically

inert and can’t readily disperse in organic solvents or aqueous

solutions, which would be disadvantageous for the assembly

and dispersion of catalytic nanoparticles. It is necessary

to functionalize CNTs in order to improve their surface

properties and dispersions in solvents. We have reported the

functionalization of CNTs with conducting polymers such as

poly(3,4-ethylenedioxythiophene) (PEDOT) and polyindole

(PIn) and used these nanocomposites as the support materials

of Pt nanoparticles. It is found that the conducting polymer

functionalization of CNTs not only remarkably enhanced the

solubility of CNTs but also introduced homogeneous surface

functional groups on the CNT surface. The conducting polymer

functionalized CNTs supported Pt nanocatalysts, exhibit

much higher electrocatalytic activity and stability than the Pt/

CNTs and commercial Pt/C catalysts for methanol oxidation.

Moreover, we have developed a novel strategy for the synthesis

of sulfur-doped or sulphur and nitrogen co-doped CNTs as the

highly efficient Pt-based catalyst support toward methanol

oxidation. The doped CNTs were obtained by annealing

PEDOT or PEDOT-based copolymer functionalized CNTs.

The results indicate that the doped CNTs could significantly

improve the dispersion of supported Pt nanoparticles and

increase the electrochemically active surface area. The doped

CNTs supported Pt-based catalysts exhibit much higher

electrocatalytic activity, long-term durability and CO-tolerance

ability for the methanol oxidation reaction compared to the

undoped CNT supported Pt and commercial Pt/C catalysts.
