The closed topology and tubular structure of carbon
nanotubes[13]
make them unique among different carbon
forms and provide pathways for chemical studies. A num-
ber of investigations[48]
have been carried out to find appli-
cations of nanotubes in catalysis, hydrogen storage, interca-
lation, etc. Since carbon-electrode-based fuel cells have
been experimented with for decades, it is of importance to
learn the electrodic performance of these new carbon
structures. We report here results of the electrocatalytic re-
duction of dissolved oxygen (important H2O2 fuel cell re-
action), using microelectrodes constructed from multi-
walled nanotubes. In parallel, ab initio calculations were
