Description

technical field

[0001] The invention belongs to the field of nanometer materials, and relates to a pure-phase and precious metal-loaded brookite titania nanocrystal photocatalytic material with special exposed crystal planes and a preparation method thereof. Background technique

[0002] Due to the small size effect, quantum size effect, surface effect, dielectric confinement effect, and macroscopic quantum tunneling effect, nanomaterials exhibit special properties different from macroscopic materials in terms of catalysis, magnetism, electricity, and optics. With the help of the special properties of nanomaterials, the application of semiconductor materials in the fields of light, electricity, magnetism, and sensors has been greatly expanded. Among them, titanium dioxide, as a class of widely used semiconductor materials, plays an important role in the fields of catalysis and photocatalysis, white pigments and cleaning coatings, and dye-sensitized solar cells. In recent ye...
