摘要	The development of inexpensive and robust bifunctional reversible oxygen electrocatalysts is critical to rechargeable metal-air batteries and regenerative fuel cells. Here we reported a single-wall carbon nanotube (SWCNT) conductive network embedded in porous N, P co-doped carbon (SWCNT@NPC) as a bifunctional oxygen electrocatalyst. The SWCNT@NPC material showed excellent electrocatalytic activity with an oxygen reduction half-wave potential of 0.85 V and oxygen evolution potential of 1.678 Vat 10 mA cm(-2). When used to assemble rechargeable Zn-air batteries, SWCNT@NPC exhibited better catalytic activity as well as durability compared to commercial noble-metal catalysts. In particular, it is demonstrated that mutual promotion between N and P doping induces ultrahigh ORR activity while N doping is identified as the primary active sites for the OER.
