Abstract
Mesoporous carbon (MC)-supported PtCo catalysts were prepared by a sodium borohydride (NaBH4) reduction method. To increase the alloy degree of PtCo catalyst, the heat treatment was carried out at various temperatures (300-700 ℃). The heat-treated PtCo catalysts (PtCo/MC-x) had the higher degrees of Pt-Co alloy than that of as-synthesized PtCo catalyst (PtCo/MC). MC supported-PtCo catalyst (PtCo/MC-500) that was treated at 500 ℃, had the highest activity and lowest overpotential in oxygen electro-reduction (ORR) among the prepared PtCo catalysts. The high alloy degree and favorable chemical states of PtCo/MC-500 are believed to be responsible for the superior activity in oxygen electroreduction compared to the other PtCo catalysts.
