dc.description.abstract | Oxygen reduction reaction (ORR) catalysts, Pd3Pt1 nanoparticles with methanol tolerance, are supported on various carbon supports: mesocellular carbon foam (MSU-F-C), CMK-3, and Vulcan XC-72. The particle size of Pd3Pt1 (similar to 5 nm) is larger than the pore size of CMK-3 (similar to 3 nm), resulting in the agglomeration of Pd3Pt1 nanoparticles on the external surface of the CMK-3. The large surface area and large pore size of MSU-F-C allows a high degree of dispersion of Pd3Pt1 nanoparticles inside the pores. Due to its highly dispersed state, the Pd3Pt1/MSU-F-C shows higher ORR activity than Pd3Pt1/Vulcan XC-72 and Pd3Pt1/CMK-3. The charge transfer resistance (R-ct), as measured by electrochemical impedance spectroscopy, increases in the order of Pd3Pt1/CMK-3 > Pd3Pt1/Vulcan XC-72 > Pd3Pt1/MSU-F-C, Pd3Pt1/MSU-F-C is methanol tolerant at 400 rpm in the presence of 0.5 M CH3OH, while methanol oxidation peaks are observed in the case of Pd3Pt1/Vulcan XC-72 and Pd3Pt1/CMK-3.
