Fig. 5. (a) HOR polarization curves of E-Pt-CNT@SnO2, Pt-CNT@SnO2 and commercial Pt/C in H2-saturated 0.1 mol·L-1 HClO4 (rotating speed, 1600 rpm; scan rate, 5 mV· s−1). (b) Micro region (-0.01 V - 0.01 V) of polarization curves. (c) Tafel plots of the kinetic current densities. (d) Comparison of mass and specific activities. (e) chronoamperometric curves with 10,000 ppm CO.
