The invention belongs to the technical field of nano metal oxide, and particularly relates to a sheet metal oxide nano material prepared based on a straw core. The sheet-shaped nano structure has the characteristics of larger specific surface area, stable physicochemical property, mechanical flexibility and the like, is more suitable for being applied to electrocatalysis, but the preparation method of the sheet-shaped nano metal oxide which is efficient and can be prepared in large quantity still faces the challenge at present. The invention provides a method for preparing a flaky metal oxide nano material based on a straw core, which is used for preparing a large amount of flaky nano metal oxide by a secondary calcination method by introducing a strategy of combining the straw core and metal ions without increasing the process flow. |
