A controllable flower-like FeMoO4/FeS2/Mo2S3 composite as efficient sulfur host for lithium-sulfur batteries

ZIF-67 derived hierarchical hollow Co3S4@Mo2S3 dodecahedron with an S-scheme surface heterostructure for efficient photocatalytic hydrogen evolution

“…63 Similarly, in the energy band diagram of Mo 2 S 3 , since the energy band of the Mo d orbitals runs through the entire region, there is no obvious band gap structure from the theoretical calculation results, which is consistent with the metal-like properties shown by Co 3 S 4 . 64…”

Reasonably Introduced ZnIn2S4@C to Mediate Polysulfide Redox for Long-Life Lithium–Sulfur Batteries

“…For addressing the issues above, promising sulfur hosts have been designed to construct advanced LSBs. − Because of possessing nanopores, the conductive carbon host such as the carbon nanotube, , the carbon nanorod, , carbon spheres, and graphene , can physically restrict LPSs from escaping to the electrolyte. However, the stability of these carbon-based sulfur electrodes decays obviously during long-term cycling, mainly resulting from friable interactions between polar LPSs and nonpolar carbon. − Therefore, various polar materials such as metal oxides, − metal sulfides, − metal nitrides, metal carbides, , and heteroatoms ,, have been introduced into carbon materials to overcome the mentioned problems and improve the cycling stability based on their strong interaction with LPSs. Thus, combining the anchoring effects of these polar materials and the conductivity of carbon materials, the polysulfides can be fixed and reduced efficiently, resulting in high sulfur utilization.…”

Bimetallic Co–Mo sulfide/carbon composites derived from polyoxometalate encapsulated polydopamine-decorated ZIF nanocubes for efficient hydrogen and oxygen evolution

“…4A and A1–A3, sample CoMoS-600 contains large amounts of curved lattices and grain boundaries. The lattice spacing of three kinds of nanoparticles are found as labelled in the images, where a d -spacing of 0.56 nm corresponds to Mo 4 O 11 ; 49 0.54 nm belongs to Mo 2 S 3 , 50 while 0.62 and 0.29 nm are related to CoMoS 3.13 . 51 The interlayer distances of CoMoS 3.13 vary in the range of 0.62–0.75 nm, which could be due to the formation of large amounts of lattice distortions and defects in the 1–3 layers of CoMoS 3.13 crystals, which may benefit the electrochemical performance.…”
