摘要：

Fluorine-doped mesoporous carbons (F/Cs) were prepared by a simple hard-template method. The pyrolysis of polytetrafluoroethylene (PTFE) supported on SBA-15 silica at high temperatures resulted in the formation of mesoporous structures with graphitic pore walls. The F/Cs obtained at 1000 degrees C possessed a surface area of 504 m(2) g(-1) and a pore size distribution centered at 6.7 nm. Such F/Cs exhibited a comparable catalytic activity for oxygen reduction reaction (ORR) to that of commercial platinum/carbon (Pt/C) catalysts and better stability and methanol-tolerance in alkaline solutions.
