Abstract

The invention discloses a Co3O4@PEDOT porous nanorod material with a core-shell structure and a preparation method of the Co3O4@PEDOT porous nanorod material. Co3O4@PEDOT is of a heterogeneous core-shell structure; a Co3O4 nanorod is taken as a core, PEDOT nanoparticles are taken as a shell, the PEDOT nanoparticles are densely attached to a Co3O4 nanorod core layer and a coarse porous structure is formed on the surface. The adopted preparation method comprises the steps of firstly preparing a Co3O4 nanowire with a core structure through a hydrothermal method; covering the surface of the Co3O4 nanowire with a layer of PEDOT particles through an electrochemical deposition method; and finally obtaining a Co3O4@PEDOT nanorod with the core-shell structure. The prepared Co3O4@PEDOT nanorod material is of a multistage structure which is formed by compounding two nano structures and is of a novel nano heterostructure; active sites of reaction are increased by a novel interface and large specific surface area of the nanorod material; the reaction characteristics of the nano composite material can be improved; and the application prospect in the fields of energy storage, catalysis and sensing is expanded.
