Thus, a lot of well-align MWNTs are fabricated on carbon cloth directly. The method in the cathode electrode of DMFC is easy to constructed and sticking on the carbon cloth tightly. Then, MWNTs are modified by HNO3, H2SO4, and KOH at high temperature may produce different functional groups to attract more Pt ions nucleating uniformly and densely. Moreover, there are the other parameters, temperature, time, and concentration, in the function of chemical modification for MWNTs. In this way, we would find 14M-MWNTs at 6 hours by using FTIR, XPS, EDX, and CV may produce a lot of functional groups to increase Pt anchoring sites. Finally, it could improve the efficiency of half-cell test.
