The invention discloses a PVA pyrolysis-coated carbon-coated zinc cobalt oxide nano-array material, a preparation method and an application thereof. Polyvinyl alcohol is used as a carbon-coated carbon source, and carbon is coated on the surface of the zinc cobalt oxide nano-array. After the metal cobalt salt, ammonium fluoride, urea and metal zinc salt are mixed, the metal cobalt salt is a divalent cobalt salt, and then the zinc cobalt oxide nano-array material is obtained by hydrothermal reaction and heat treatment; After heat treatment, the carbon-coated zinc cobalt oxide nano-array material is obtained by PVA pyrolysis. The PVA pyrolysis-coated carbon-coated zinc cobalt oxide nano-array material prepared by the invention has excellent electrochemical sodium storage performance, and the preparation method is simple in process, low in cost and easy to popularize. |
