Abstract

See full text

The present invention relates to the technical field of functional materials, and in particular to an amorphous metal oxide hollow multi-shell material and a preparation method therefor and an application thereof. The method includes the following steps: 1) performing a heating reaction on a carbon source aqueous solution, filtering, washing, and drying to obtain a carbon sphere template; 2) dispersing the carbon sphere template obtained in step 1) in a first metal salt solution, heating, adsorbing, and drying to obtain a first solid precursor; 3) dispersing the solid precursor obtained in step 2) in a second metal salt solution again, adsorbing, and drying to obtain a second solid precursor; and 4) calcinating the second solid precursor obtained in step 3) to obtain the amorphous metal oxide hollow multi-shell material. According to the present invention, a defect-controllable doping energy level is introduced into a metal oxide hollow sphere by means of a two-step enhanced adsorption method, so that efficient absorption of wave bands in a solar spectrum is achieved.
