Abstract

The invention provides a nanometer metal oxide and a preparation method thereof, and belongs to the field of nanometer inorganic compound photocatalytic materials and dyestuff manufacturing techniques. The present invention selects halides or inorganic salts containing metal ions as the source of metal ions, selects complexing agent, sucrose, glucose, acrylamide, bisacrylamide, agar, gelatin and carboxymethyl cellulose as gel raw materials, and evenly disperses the metal Ions, use industrial irradiation equipment to irradiate the raw material solution or emulsion to form a gel with a spatial network structure, and prepare nanoscale metal oxides through the later grinding and sintering processes. These nanoscale metal oxides can be used as excellent photocatalysts or dyes. The preparation method of the invention is simple, the process is stable, the operability is strong, the consumption of gel raw materials is greatly reduced, no heating is required, no special treatment of raw materials is required, and industrial irradiation devices can be used for mass production.

Description

technical field

[0001] The invention relates to a nanometer metal oxide and a preparation method thereof, and belongs to the technical field of nanometer inorganic compound photocatalytic materials and dyestuff manufacturing techniques. Background technique

[0002] Nanomaterials have unique quantum size effects, small size effects, surface effects and macroscopic quantum tunneling effects, and usually exhibit outstanding activity in catalytic reactions and dye printing and dyeing. In recent years, due to the excellent performance of metal oxide nano-photocatalysts and dyes, the application in environmental treatment and printing and dyeing has attracted more and more attention. The traditional methods for preparing nano-photocatalysts and dyes mainly include chemical sol-gel method, hydrolysis precipitation method, solid-phase method, hydrothermal synthesis method, microemulsion method, etc. Among them, the preparation process of chemical sol-gel method is relatively simple...
