Platinum (Pt) catalysts supported on CMK-3 have been prepared as catalysts for PEM fuel cells. Mesoporous carbon molecular sieve, CMK-3 is a interesting material due to its uniform pore diameter, high surface area, high thermal and chemical stability. CMK-3 is synthesized from silica template (SBA-15) and furfuryl alcohol (FFA) as the carbon source. H2PtCl6•xH2O is used as pt precursor and pt nanoparticles are successfully deposited onto CMK-3. Pt/CMK-3 is characterized by XRD, TEM, TG/DTA and BET and the cell test is conducted for the MEA fabricated with different ratio of Pt/CMK-3 and Pt-CB hybrid catalysts. |
