MXene-Based Hierarchical Electron Coupling Engineering of F-Doped NiFe LDH/MOF-74 Electrocatalysts for Efficient Overall Water Splitting

Enhancing the intrinsic activity and exposing the real active sites in transition metal-based electrocatalysts are still a formidable challenge. In this work, we introduce an efficient partial in situ transformation strategy (PTS) that converts the NiFe MOF-74 precursor into NiFe LDH@MOF composite structure, and subsequently the incoming F coordinates accelerate the structural reconstruction of F-doped NiFe LDH@MOF on MXene (Fd-PTS-NLM) during overall water splitting. The electrocatalytic mechanism exploration reveal that the rate of electron transfer in a material can be modulated by manipulating the electron diffusion process, thereby reducing the energy barrier associated with catalytic reactions.
