Synergistically enhanced oxygen reduction activity of MnOx-CeO2/Ketjenblack composites

摘要

Here we report a hybrid of MnOx-CeO2/Ketjenblack as a novel catalyst for oxygen reduction reaction (ORR) by a facile strategy. This hybrid exhibits comparable activity and better stability towards ORR than the commercial 20 wt Pt/C due to the synergistic effect.
