A Ce-MCM-48 molecular sieve was prepared by the hydrothermal synthesis method. Using Ce-MCM-48 as the support, a series of MoO Pd/Ce-M catalysts were prepared by the impregnation method by introducing MoO and Pd. XRD, N adsorption desorption, SEM, TEM, NH-TPD, Py-IR, FT-IR, and ICP-MS were used to characterize the physicochemical properties.

Herein, a facile and controllable strategy using a binary Ni-Co metal-organic framework (MOF) precursors followed by the selenization process, which produced a cobalt nickel selenide/N-doped carbon composite ((CoNi)Se/NC) that maintained the hierarchical nanospheres structure. Such a distinctive structure affords both Na and electron diffusion pathways in the electrochemical reactions as well as high electrical conductivity, thus leading to superior electrochemical performance when the designed composite is utilized as an anode in SIBs.
