Fig. 3: Experimental ORR activities of Pt1Ni1@Pt/C, Pt3Ni1@Pt/C, syn-Pt/C, and com-Pt/C.
From: Carbon-anchoring synthesis of Pt1Ni1@Pt/C core-shell catalysts for stable oxygen reduction reaction
a Aberration-corrected HADDT-STEM image of Pt1Ni1@Pt/C and syn-Pt/C NPs. b HADDF intensity profile of Pt1Ni1@Pt/C and syn-Pt/C. c iR corrected ORR polarization curves (d) Tafel plots, e CV curves, and f specific and mass activities of different catalysts measured in 0.1 M HClO4. The error bars indicate the standard deviation, derived from at least three independent measurements. iR correction was conducted at 100% manually.
