英文摘要	NSFC [21273180, 60936003, 21021002, 20833005]; NFFTBS [J1030415]; Well-dispersed PtBi intermetallics supported on the modified mesoporous carbon-46 (PtBi/MPC) has been synthesized by using hydrogen gas to reduce the platinum and bismuth precursors. The results of TEM, XRD, EDX, and XPS exhibited that PtBi nanoparticles are intermetallics. Electrochemical characterization revealed that PtBi/MPC showed extremely high mass activities and stability towards oxidizing of formic acid. These high performances may attribute to synergistic effects of electron and geometry effects of these intermetallics and the specific properties of MPC. With the reported promotional effect of Bi, such Pt-based intermetallics supported on MPC is a promising anode catalyst for direct formic acid fuel cells. (C) 2012 Elsevier B.V. All rights reserved.
