ORR characteristics of electrocatalysts.

(A) CV of Photo-Pt-Graphite-TiO2 and Photo-Pt-CNT-TiO2 in N2 saturated 0.1 M HClO4 aq. at scan rate of 50 mVs−1. (B) ECSA calculated from the CVs and comparison with commercial material. (C) RDE linear sweep voltammograms for all the samples under study and (D) Mass activity and Specific activity obtained from K-L plots at 0.90 V vs RHE.
