Key Points

  • The study aims to synthesize and compare the electrocatalytic activities of two metal-free COFs in oxygen evolution and reduction reactions.
  • Synthesis of two COFs: BTTh-TZ-COF and TPA-TZ-COF
  • Evaluation of bifunctional activities in oxygen evolution and reduction
  • Assessment of charge transport and energy barriers
  • BTTh-TZ-COF shows superior bifunctional activity compared to TPA-TZ-COF
  • Enhanced charge transport in BTTh-TZ-COF leads to lower energy barriers
  • Improved performance in rechargeable zinc-air batteries

Abstract

Two low-bandgap, metal-free donor–acceptor COFs (BTTh-TZ-COF and TPA-TZ-COF) are synthesized to compare bifunctional OER/ORR activities. The N and S-containing BTTh-TZ-COF exhibits superior charge transport, active sites, and lower energy barriers,...
