Controllable Construction of Bifunctional CoxP@N,P-Doped Carbon Electrocatalysts for Rechargeable Zinc-Air Batteries
文献摘要：
The exploration of cheap,efficient,and durable bifunctional electrocatalysts for oxygen reduction reaction(ORR)and oxygen evolution reaction(OER)is highly desired to push forward the commercialization of rechargeable metal-air batteries.Here,bifunctional ORR/OER electrocatalysts based on CoxP(0＜x＜2,i.e.,Co2P,Co2P/CoP mixture,and CoP)nanoparticles(NPs)anchored on N,P-doped carbon framework(CoxP@NPC)are developed via one-step carbonization of the mixture of as-synthesized ZIF-67 and melamine-phytic acid supermolecular aggregate(MPSA).The stoichiometric ratio of resultant CoxP NPs can be rationally designed by adjusting the introduced ratio of ZIF-67 to MPSA,enabling their fabrication in a controlled manner.It is found that the as-synthesized Co2P@NPC exhibits the best bifunctional ORR/OER activity among the CoxP@NPC analogues,with a reversible oxygen electrode index(AE=Ej10-E1/2)down to～0.75 V.The constructed Zn-air battery based on Co2P@NPC delivers a peak power density of 157 mW cm-2 and an excellent charge-discharge stability with negligible voltage decay for 140 h at 10 mA cm-2,superior to those based on Pt/C+RuO2 and most CoxP-based electrodes ever reported.
