Problems solved by technology

[0003] At present, there are many methods for preparing iron-based nanomaterials. For example, Chinese patent application No. 201410388257.9 discloses a method for preparing nanopillars, and Chinese patent application No. 201310012124.7 discloses a method for preparing nanoribbons; However, there is no preparation method that can make the size of iron-based nanosheets controllable in the prior art. If the size of the produced iron-based nanosheets can be controlled, it will give a new opportunity to the application of iron-based nanosheets in product miniaturization. provide great convenience
