抜粋

Pt/Nb-SnO2/VGCF-H electrocatalysts have been developed with Ft impregnated on the SnO2-based supports dispersed on carbon nanofiber acting as a conductive backbone, achieving both high catalytic activity and high voltage-cycle durability. In this study, we have focused on Pt alloying with Co and Ni and developed Pt3Co/Nb-SnO2/VGCF-H electrocatalysts for achieving higher oxygen reduction reaction (ORR) activity. It has been confirmed that catalyst particles were selectively impregnated on the doped-SnO2 and Pt3Co alloying was verified by FESEM and high-resolution STEM. High mass activity (MA) of 273 A g-1 at 0.9 VRHE and of 1870 A g-1 at 0.85 VRHE has been achieved for the Pt3Co catalyst on the Nb-doped SnO2 support, after proper heat treatment. High voltage cycle durability by applying the SnO2-based supports has also been verified.
