The invention provides a transition metal compound nanosheet and a preparation method and application thereof, wherein the preparation method of the nanosheet comprises the following steps: mixing soluble salt containing transition metal elements with urea, adding water, stirring uniformly, transferring to a reaction kettle for hydrothermal reaction, and centrifuging to obtain layered metal hydroxide; dispersing the layered metal hydroxide in a solution containing acid radical ions, centrifuging, and calcining to obtain the nanosheet. According to the preparation method, the specific acid radical anions can be controllably adsorbed between the layered metal hydroxide laminates by utilizing the characteristic that specific acid radical anions can be adsorbed due to positive charges between the layered metal hydroxide laminates, the preparation of the transition metal compound nanosheets realized by utilizing topological transformation is realized by pyrolysis, uniform and stable acid radical anions can be adsorbed in the layered metal hydroxide laminates by controlling reaction conditions, controllable transformation of degree is realized after pyrolysis treatment, and finally the improvement of performance in application is realized. |
