a XRD patterns of post np-Pt and fresh np-Pt. b High-resolution Pt 4 f XPS spectra of fresh np-Pt and post np-Pt. c XANES spectra of post np-Pt, and Pt foil and PtO2 references at Pt L3-edge. d HR-TEM image of post np-Pt. e HAADF-STEM and the corresponding elemental (Pt, O) mapping images of post-np-Pt. f Quasi-in situ Raman spectra of np-Pt after electrolysis at 100 mA cm−2 in 2.0 M PA electrolyte (pH = 10.0  ±  0.2) for different time. Source data are provided as a Source data file.
