The issues of polysulfide shuttling and lethargic sulfur redox reaction (SROR) kinetics are the toughest obstacles of lithium–sulfur (Li–S) battery. Herein, integrating the merits of increased density of metal sites and synergistic catalytic effect, a unique single‐atom catalyst (SAC) with nonmetallic‐bonding Fe–Mn diatomic pairs anchored on hollow nitrogen‐doped carbonaceous nanodisk (denoted as...
Sluggish sulfur redox reaction (SROR) kinetics accompanying lithium polysulfides (LiPSs) shuttle effect becomes a stumbling block for commercial application of LiS battery. High‐efficient single atom catalysts (SACs) are desired to improve the SROR conversion capability; however, the sparse active sites as well as partial sites encapsulated in bulk‐phase are fatal to the catalytic performance. Herein,...
A universal strategy is established for preparing the carbonaceous matrix‐based atomically distributed metal catalysts M‐BPC (M=Ni, Co, Fe, Cu, and Mn, and biomass‐derived porous carbon (BPC)) by one‐step pyrolysis of mixed metal salts and biomass alfalfa. The optimized Ni‐BPC has dual‐atom Ni(II)2N4(µ2‐N)2 moieties, which are chemically anchored on the alfalfa‐derived developed porous N‐doped carbon...
