Abstract
⺠The Co-pda-derived material (900 °C) is a better ORR catalyst than the Co-en-derived material (700 °C). ⺠The Co-pda-derived catalyst, the transfer coefficient (α) is â¼1 and no pH dependence of the ORR rate at pH < 2.6. ⺠A possible mechanism for the ORR at pH < and > 2.6 was presented. ⺠The ORR was examined as a function of solution temperature (12-62 °C). ⺠It was also found that the catalyst was unstable at solution temperatures above around 50 °C.
