Platinum catalysts supported on ordered mesoporous carbons (OMCs) have been prepared as catalysts for PEM fuel cells. Highly ordered mesoporous carbon was synthesized successfully via a direct carbonization of self-assembled F127 and resorcinol-formaldehyde composites and platinum then was deposited . Before the platinum deposition, carbon support surface was treated using HNO3 and H2SO4 as oxidizing agent. OMCs containing Pt were prepared and characterized by FT-IR, BET, TGA, XPS, XRD and TEM analysis. Structural and morphological analyses of the samples showed that the typical ordered mesoporous structure of OMCsis maintained after Pt deposit. The TEM analysis of the samples showed a homogeneous dispersion of platinum particles. |
