a, b, Spectra of PdHx@Pt NS (a) and Pt/C (b) measured under steady-state conditions. c, d, Comparisons of XANES spectra collected at 0.3 V for PdHx@Pt NS (c) and Pt/C (d) during different scan directions. The 0.3 V during anodic scan indicates the initial potential when the potential was ramped from 0.3 V to 1.1 V. The 0.3 V during cathodic scan means the applied potential when it decreased from 1.1 V to 0.3 V.
