This project focuses on the core demands of the new energy field, taking green and low-carbon development as the orientation, developing non-precious metal catalytic materials and intelligent energy storage devices, and realizing industrialization. At the material level, it innovatively develops perovskite-type bimetallic nitride and NiFe-MOF composite core-shell structured electrodes, which enhance electrocatalytic activity through interfacial coupling effects, with HER and OER overpotentials a
