Double-layer ZnO hollow sphere photocatalytic material and preparation method thereof

Abstract

The present invention belongs to the technical field of photocatalytic materials and preparation thereof, and more particularly, relates to a double-layer ZnO hollow sphere photocatalytic material. The double-layer ZnO hollow sphere photocatalytic material is formed by inner and outer layers of ZnO hollow spheres; the hollow spheres on the inner layer have a diameter of 1.0-2.5 μm; and the hollow spheres on the outer layer have a diameter of 1.5-4.5 μm. The present invention further relates to a preparation method of the double-layer ZnO hollow sphere photocatalytic material, which comprises the following steps of: dissolving dissolvable zinc salt into a mixture of monohydric alcohol and ethylene glycol to prepare a solution, and then performing a solvothermal reaction on the solution under airtight conditions to prepare the double-layer ZnO hollow sphere photocatalytic material.
