(a) Dark-field images of Au@Pt assembly immobilised on an ITO glass with respect to cycle number of CV. Scale bars for dark field images are 20 μm. (b) LSPR spectra of Au@Pt assembly with respect to cycle number of CVs. (c) Plots of the LSPR spectral wavelengths (λmax) and their intensities at λmax as a function of cycle number of CVs. (d) CVs for Au@Pt nanoparticles during the 400 cycles with a scan rate of 30 mV sec−1 in 0.1 M HClO4. (e) Calculated electrochemically active surface area (ECSA) as a function of cycle number of CVs. The showing cycle numbers for (b) and (d) were 10, 20, 50, 100, 150, 200, 250, 300, 350, and 400 as the direction of the arrows.
