Abstract

The invention relates to a carbon/copper/metal oxide composite porous material and a preparation method and application thereof. The composite porous material is of a composite structure consisting of carbon, metal copper nano particles and metal oxide nano particles; in the composite structure, the metal oxide nano particles are stacked to form a three-dimensional porous skeleton; the metal copper nano particles are attached to the metal oxide nano particles; and the carbon wraps the surfaces of the metal copper nano particles and the metal oxide nano particles. The invention also provides a preparation method and application of the composite porous material. According to the carbon/copper/metal oxide composite porous material and a preparation method and application thereof provided by the invention, the reaction conditions are mild, the preparation process is simple and easy to implement and environment-friendly, the components are controllable, the output is high, and large-scale production is easy to realize; and due to the addition of the carbon and copper nano component, the prepared carbon/copper/metal oxide composite porous material obviously improves the electrical conductivity and is favorable for the functionalization application of the metal oxide nano material.

Description

technical field [0001] The invention belongs to the technical field of nanomaterial preparation, and relates to a carbon / copper / metal oxide (C / Cu / MO, M=Zn, Mn, Cd, Fe, Ni) composite porous material and its preparation method and application. The composite porous material can be used as the negative electrode material of lithium ion battery. Background technique [0002] Composite nanomaterials are achieved by effectively integrating different nanomaterials together to obtain synergistic effects between materials in addition to the physical and chemical properties of a single material. Among them, the nanocomposite structure of metals and inorganic substances has been widely studied and applied in the fields of energy storage, industrial catalysis, functional ceramics, and biopharmaceuticals because of the combination of the high electrical conductivity of metals and the inherent physical and chemical properties of inorganic materials. For example, in the field of lithium-io...
