From: Identifying the distinct roles of dual dopants in stabilizing the platinum-nickel nanowire catalyst for durable fuel cell

Fig. 1

HAADF-STEM images and EDS EDS line-scanning profiles of a PtNi NWs, b PtNiMo NWs, and c PtNiAu NWs. d XRD patterns of PtNi-bassed NWs. e MA and f ECSAs for different NWs/C catalysts after different cycles. Dissolving mass of g Pt and h Ni metals for PtNi-based NWs/C catalysts after different cycles. i Dissolving rate of Pt and Ni metals for PtNi-based NWs/C catalysts after 20 K cycles. All dissolving mass and dissolving rate values are means with error bars (standard deviations) from three replicates.
