Constructing MoS2-SnS heterostructures on N-doped carbon nanosheets for enhanced catalytic conversion of polysulfides in lithium-sulfur batteries

A bimetallic sulfide MoS2-SnS heterostructure has been constructed by a salt-template method to modify the separator of Li-S batteries. The 3D porous MoS2-SnS heterostructure on N-doped carbon (MoS2-SnS/NC) can improve the LiPSs adsorption and accelerate the LiPSs conversion and Li2S uniform nucleation/deposition due to its pore structure, polar bond, and excellent catalytic properties.
