Figure 4. (A) LSV curves of Pt plate and CS-8t samples with various numbers of indents, showing their ECSA-normalized activities. (B) Linear fits of η10 and TOF values with number of indents. (C) Nyquist plots of Pt plate and CS-16 sample. (D) Stability tests of Pt plate and CS-16 sample using CP and (inset) SEM image of an indent (scale bar: 500 μm).
