4. Conclusions
In summary, we have successfully synthesized Se nan-
otubes by the electrochemical method using CTAB as soft-
template. The result showed that the function of CTAB for
the formation of Se nanotubes is essential. XRD and LRS
indicate that the nanotubes were made up of pure trigonal
phase of Se. Interestingly, the ramified growth of Se nan-
otubes was firstly observed. The electrochemical study re-
sults of the products indicate that the discharge behavior of
Se nanotubes is excellent. The products with various mor-
phologies were also obtained by changing experimental con-
ditions. The synthesis designed is simple and controllable,
and may be used to prepare other nanostructures.

results are shown in Fig. 6. From the voltammograms, it can
be seen that the electrochemical behavior of Se nanotubes is
trode. Espinosa et al. [20] had found that the electrochemical
oxidation behavior of two Se forms (gray crystal Se and red
amorphous Se) is different on carbon paste electrode. Wei
havior of these two forms of Se is unlike on Au electrode.
Here we observed that the oxidation peak (+1.09 V) of Se
nanotubes is much higher than that (+0.85 V) of amorphous
Se nanoparticles (as shown in Fig. 6a). This peak can be
chemical reduction wave of Se nanotubes is analogy with that
of amorphous Se nanoparticles according to the electrode re-
action of Se(0) to Se(−II), but the reduction current of Se
nanotubes is much larger (as shown in Fig. 6b). Based on the
voltammograms, we can get a result that the discharge behav-
ior of Se nanotubes is excellent compared with amorphous Se
nanoparticles.
