Figure 1.  CVs measured in (A) deaerated 0.5 M H2SO4 and (B) deaerated 0.5 M NaOH at (a) Pt/GC, (b) MnOx/Pt/GC (td (Pt) = 5 min  and θ (MnOx) = 52%) electrodes
Figure 2.  (A) FE-SEM image and (B) EDS spectrum of MnOx/Pt/GC electrode. Nano-Pt and nano-MnOx were electrodeposited at the GC surface as mentioned in the caption of Fig
Fig. 3 shows the impact of nano-MnOx loading level on the catalytic activity towards EGO
Table 1. Variation of the catalytic enhancement factor and the onset potential for EGO with different deposition cycles of nano-MnOx onto Pt/GC (nano-Pt loading was kept constant at 3.8 μg) in 0.5 M NaOH + 0.5 M EG
