Main-group metal and nitrogen coordinated carbons (M-N-Cs) are promising but remain largely underexplored due to the low metal-atom density and the lack of understanding in the structure-property correlation. Here, we report using a nanoarchitectured Sb₂S₃ template to synthesize high-density (10.32 wt%) antimony (Sb) single atoms on nitrogen- and sulfur-codoped carbon nanofibers (Sb-NSCF), which exhibits both high selectivity (97.2%) and mass activity (114.9 A g^-1 at 0.65 V) towardNature communicationsSb₂S₃-templated synthesis of sulfur-doped Sb-N-C with hierarchical architecture and high metal loading for H₂O₂ electrosynthesis.PMC98710212220904322178072921631162020JJ4204519020992020JJ1001Yan MJohannessen BLiu JZhao SHe GYe GFei HWei ZGong ZCui CfalseSb₂S₃-templated synthesis of sulfur-doped Sb-N-C with hierarchical architecture and high metal loading for H₂O₂ electrosynthesis.Selective two-electron (2e^-) oxygen reduction reaction (ORR) offers great opportunities for hydrogen peroxide (H₂O₂) electrosynthesis and its widespread employment depends on identifying cost-effective catalysts with high activity and selectivity.
