Fig. 4. Characterizations and MOR performance of Pt1/RuO2-500/Pt1/RuO2-700 and Pt1/RuO2-H in 0.1 mol L‒1 KOH and 1 mol L‒1 methanol solution at a scan rate of 50 mV s‒1.
a Typical HAADF-STEM images of Pt1/RuO2-700. b Corresponding EDS-mapping images of enlargement in (a). c Typical HAADF-STEM images of Pt1/RuO2-H. d k3-weighted R-space Fourier transformed spectra from EXAFS of Pt1/RuO2-H. e MOR performance. The curves in Figs. 2b and 3b are replotted here for convenient comparison.
