Problems solved by technology

[0003] At present, there are very few reports on the macro-preparation methods of metal / oxide composite porous materials, because several technical difficulties are faced in the synthesis process: it is difficult to control the coexistence of metal and oxide phases at high temperature; the particles, pore size, and composition of the product are different. Uniform; complex preparation process; low output, high cost; unfriendly to the environment, etc.

Abstract

The invention relates to a method for preparing a carbon-encapsulated Cu / Mn2O composite porous material. The porous material is provided with nanoscale three-dimensional pore canals; as the nano component of copper is added, the electronic conductivity of the composite material is obviously improved, which facilitates the functionalized application of the nano material of a metal oxide. The method has the advantages of simple preparation technology, controllable product components, uniform granularity, high yield and the like, and is easy for mass production.

Description

technical field [0001] The invention belongs to nanometer material technology, in particular to a preparation method of carbon-coated Cu / Mn2O composite porous material. Background technique [0002] Composite nanomaterials integrate nanomaterials with different functions together to obtain synergistic effects beyond the physical and chemical properties of a single material, such as easier functionalization of the surface, more binding sites, higher specific surface area, higher dielectric constant, change absorption band gap and catalytic activity. Among them, the nanocomposite structure of metals and inorganic substances has broad research and application prospects in the fields of energy storage, industrial catalysis, functional ceramics, and biopharmaceuticals because of the combination of high electrical conductivity of metals and inherent physical and chemical properties of inorganic materials (Shanghai Communications University Doctoral Dissertation in 2009; Desalinat...
