Tuning ZnSe/CoSe in MOF-derived N-doped porous carbon/CNTs for high-performance lithium storage

Binary metal selenides (ZnSe/CoSe) encapsulated in N-doped carbon polyhedra interconnected with carbon nanotubes (ZCS@NC/CNTs) are prepared through a simple solution method, involving subsequent in situ pyrolysis and selenization of the metal–organic framework (MOF) precursor.
