dc.description.abstract | Three-dimensional (3D) porous microspheres composed of CoSe2@N-doped carbon nanorod-deposited carbon nanotube (CNT) building blocks (CoSe2@NC-NR/CNT) can be successfully synthesized using CNT/Co-based metal organic framework (ZIF-67) porous microspheres as a precursor. This strategy involves the homogeneous coating of ZIF-67 polyhedrons onto porous CNT microspheres prepared by spray pyrolysis and further selenization of the composites under an Ar/H-2 atmosphere. During the selenization process, the ZIF-67 polyhedrons on the CNT backbone are transformed into N-doped carbon-coated CoSe2 nanorods by a directional recrystallization process, resulting in a homogeneous deposition of CoSe2@NC nanorods on the porous CNT microspheres. Such a unique structure of CoSe2@NC-NR/CNT microspheres facilitates the transport of ions, electrons, and mass and provides a conductive pathway for electrons during electrochemical reactions. Correspondingly, the composite exhibits a superior dual functionality as both an electrocatalyst for the hydrogen evolution reaction (HER) and an electrode for sodium-ion batteries (SIBs). The CoSe2@NC-NR/CNT microspheres exhibit a small Tafel slope (49.8 mV dec(-1)) and a superior stability for HER Furthermore, the composite delivers a high discharge capacity of 555 mA h g(-1) after 100 cycles at a current density of 0.2 A g(-1) and a good rate capability for SIBs. | - |
