Synergistically enhanced oxygen reduction activity of MnOx–CeO2/Ketjenblack composites†
Abstract
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.
