Seeking highly efficient, stable, and cost-effective bifunctional electrocatalysts of rechargeable Zn–air batteries (ZABs) is the top-priority for developing new generation portable electronic devices. For this, rational effective structural design, interface engineering, electron recombination on should be taken into account to reduce reaction overpotential expedite kinetics oxygen reduction (ORR) evolution (OER). Herein, we construct a MnCo-based metal organic framework-derived heterogeneous MnS–CoS nanocrystals, which are anchored free-standing porous N-doped carbon fibers (PNCFs) by in situ growth method vulcanization process. Benefiting from abundant vacancies active sites, strong interfacial coupling as well favorable conductivity, MnS–CoS/PNCFs composite electrode delivers mentionable electrocatalytic activity stability with half-wave potential 0.81 V ORR an 350 mV OER alkaline medium. Of note, flexible ZAB using binder-free air cathode offers high power density 86.7 mW cm–2, large specific capacity 563 mA h g–1, adapts different bending degree operation. In addition, functional theory calculation clarifies that nanocrystals reduces barrier enhances conductivity catalyst adsorption intermediates during This study opens up insight design self-supported

Built‐In Electric Fields and Interfacial Electron Modulation: Enhancement of Oxygen Reduction Reaction in Alkaline Seawater

Advanced Energy Materials, Journal Year: 2023, Volume and Issue: 13(48)

Published: Nov. 12, 2023

Abstract The development of an electrocatalyst for oxygen reduction reaction (ORR) in a seawater electrolyte is the key to realizing utilization marine resources and application Zn–air batteries (ZABs). Exploring adsorption desorption behavior can guide design catalysts fundamentally improve catalytic performance. On this basis, WC Co on nitrogen‐doped carbon (WC‐Co@NC) with interfacial built‐in electric field (BEF) designed as ORR catalyst. theoretical calculation certifies that BEF W─C─Co connections promote charge separation directional migration, thus equilibrium speeding up process ORR. These give WC‐Co@NC high half‐wave potential 0.872 V, alkaline seawater‐based ZAB air cathode has peak power density 188.8 mW cm −2 excellent stability. This work provide basis rational ZAB, also new direction resources.
