Despite intense research in past decades, the lack of high-performance catalysts for fuel cell reactions remains a challenge in realizing fuel cell technologies for transportation applications. Here we report a facile strategy for synthesizing hierarchical platinum-cobalt nanowires with high-index, platinum-rich facets and ordered intermetallic structure.(More)
≥99%) and oleylamine (CH 3 (CH 2) 7 CH=CH(CH 2) 7 CH 2 NH 2 , 68-70%) were all purchased from Sigma-Aldrich. Copper (II) chloride dihydrate (CuCl 2 • 2H 2 O, reagent grade), ascorbic acid (C 6 H 8 O 6 , AA, reagent grade), glucose (C 6 H 12 O 6 , reagent grade) were purchased from Sinopharm Chemical Reagent Co. Ltd. (Shanghai, China). All the chemicals were(More)
Compressive surface strains have been necessary to boost oxygen reduction reaction (ORR) activity in core/shell M/platinum (Pt) catalysts (where M can be nickel, cobalt, or iron). We report on a class of platinum-lead/platinum (PtPb/Pt) core/shell nanoplate catalysts that exhibit large biaxial strains. The stable Pt (110) facets of the nanoplates have high(More)
