Simultaneously formed and embedding-type ternary MoSe₂/MoO₂/nitrogen-doped carbon for fast and stable Na-ion storage.

ABSTRACT: To obtain an electrode material that is capable of manifesting high Na-ion storage capacity during long-term cycling at a rapid discharge/charge rate, ternary heterophases MoSe₂/MoO₂/carbon are rationally designed and synthesized through a supermolecule-assisted strategy. Through using supermolecules that are constructed from MoO₄ ^2- and polydopamine as the precursor and sulfonated polystyrene microspheres as the sacrificial template, the in situ formed ternary phases MoSe₂/MoO₂/carbon are fabricated into a hollow microspherical structure, which is assembled from ultrathin nanosheets with MoSe₂ and MoO₂ nanocrystallites strongly embedded in a nitrogen-doped carbon matrix. In the ternary phases, t
