Developing a highly stable and high-efficiency catalyst for oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) is critical to developing Zinc-air battery. In this work, a facile strategy was applied to prepared Ag-CeO2-Co3O4/C dual-functional catalyst. The interface interaction affecting the electronic structure and valence state of Ag, Ce and Co, significantly facilitates the ORR/OER catalytic activity. For the Ag-CeO2-Co3O4/C catalyst, the half-wave potential is 0.80 V and limiting current density is 6.2 mA cm(-2) in ORR, while the overpotential is 340 mV s(-1) at 10 mA cm(-...
