Abstract：

CoPS　nanoparticles　encapsulated　with　S,　P,　N　tri-doped　carbon　material　(SPNC)　were　proposed　as　bifunctional　electrocatalyst　of　oxygen　evolution　reaction　(OER)　and　oxygen　reduction　reaction　(ORR)　derived　from　zeolitic　imidazolate　framework-67.　Density　functional　theory　calculations　consistently　revealed　that　P　element　in　CoPS@SPNC　improves　the　electrical　conductivity　and　reduces　OH∗　hydrogenation　energy　barrier　on　Co　sites,　thereby　facilitating　the　overall　ORR/OER　activities.　A　flexible　Zn–air　battery　with　CoPS@SPNC　delivered　an　overpotential　of　0.49　V,　an　energy　efficiency　above　80%,　and　a　discharge　voltage　of　1.29　V　at　2　mA　cm−2　for　80　h.　©　2021　Central　South　University.
