摘要：

High energy density, low cost and ultra-stable bifunctional electrocatalysts that act simultaneously for the oxygen reduction reaction (ORR) and the oxygen evolution reaction (OER) are important for commercializing the rechargeable Zn-air batteries. Co-doped TiO2 nanoparticles as an ultra-stable and cheap electrocatalyst exhibited excellent activity for both ORR and OER in alkaline media. A real air cathode made of the Co-doped TiO2 electrocatalyst further offered superior high energy density (778 mA h g(Zn)(-1) and 938.5 W h kg(Zn)(-1) at 5 mA cm(-2), and 785.9 mA h g(Zn)(-1) and 911.3 W h kg(Zn)(-1) at 20 mA cm(-2)) and ultra-high stability (37 cycles for 750 h of operation at 20 mA cm(-2) and 3150 cycles for 1050 h of operation at 5 mA cm(-2)) in two-electrode Zn-air batteries.
