Fig. 3. (a) CO-stripping curves of Pt/C, Pt-CNT@SnO2 and E-Pt-CNT@SnO2 in 0.1 mol·L-1 HClO4 (scan rate: 20 mV·s−1). The solid and dotted lines represent the data from the first and second cycles, respectively. (b) Comparison of ECSA calculated from different methods for Pt/C, Pt-CNT@SnO2 and E-Pt-CNT@SnO2. (c) Schematic illustration of the selective permeability of encapsulation layer due to the electrochemical-induced SMSI.
