Carbon-supported cobalt polypyrrole

Lee K, Zhang L, Lui H, Hui R, Shi Z, Zhang J (2009) Oxygen reduction reaction (ORR) catalyzed by carbon-supported cobalt polypyrrole (Co-PPy/C) electrocatalysts. Electrochim Acta 54 4704 711... 

The half-cell shown in Fig. 12.1 can also be used for evaluating non-Pt-based catalysts. For example, Lee et al. [2] investigated the ORR kinetics and mechanisms on carbon-supported cobalt polypyrrole (Co-PPy/C) catalysts by using both RDE and RRDE techniques. Figure 12.5 presents the ORR current-voltage (I-V) curves in 0.5 M H2SO4 with several Co-PPy/C catalysts, which shows that the catalyst heat treated at 800 °C can yield the highest catalytic...
