Three-dimensional layered conductive MOF/LDH/CNF composite electrode material and preparation method and application thereof

The invention discloses a three-dimensional layered conductive MOF/LDH/CNF composite electrode material and a preparation method and application thereof, and belongs to the technical field of electrode materials. The preparation method comprises the following steps: by applying a design thought of a composite material, growing LDHs on oriented carbon fiber cloth to construct a tightly coupled and uniformly distributed lamellar LDH nano array, and then adding a multidentate organic ligand to convert the LDH part on the surface into conductive MOFs with rapid charge migration and strong oxidation-reduction activity, so as to obtain the conductive MOFs/LDHs composite material. And finally, the MOF/LDH/CNF electrode material with the three-dimensional layered nano heterostructure is constructed. The designed three-dimensional heterostructure perfectly inherits the flexible structure and conductivity of two-dimensional conductive MOFs, retains the diversity and inherent catalytic activity of LDH, and also has rapi
