Several methods for loading of Pt-Ni binary catalysts on the CNTs were tested. Using the
CNTs treated HNO3, the catalysts supported Pt, Ni separately(Pt&Ni/CNT) and Pt-Ni alloy(Pt-
Ni/CNTs) were made respectively. The results of supporting were confirmed by TEM and XRD
analysis. TEM images show that metal catalysts were loaded uniformly and finely on the CNTs. By
XRD analysis, the peaks of Pt&Ni/CNTs displayed Pt and Ni peaks respectively. Also it was found
that the peaks of Pt were shifted to the higher 2theta angle in X-ray diffraction pattern which
indicated that Pt-Ni alloy was formed successfully(Pt-Ni/CNTs). In addition, electrochemical tests
for cathode catalysts of DMFC were performed. As the results, Pt-Ni/CNTs was most suitable for
cathode catalysts of DMFC.
