In this work, ordered mesoporous carbons (OMCs) were prepared by conventional templating method using SBA-15 as a catalyst support in fuel cells. And the effect of melamine treatment on carbon supports (M-OMCs) was investigated with different melamine amounts, i.e., 0, 1, 3, 4, and 5 g per OMCs 1 g. The nitrogen functional groups of the carbon supports were increased with an increase in the amounts of melamine, while the average Pt-Ru nanopaticle size decreased owing to the improvement of dispersibility of the Pt-Ru catalysts. As a result, the electrochemical activity of surface treated OMCs supports was enhanced by the melamine. |
