Abstract

The invention discloses a preparation method for an anatase titanium dioxide nanocrystalline mesoporous microsphere. A butyl titanate alcoholic solution is prepared from butyl titanate and alcohol; a gelatin solution is prepared by gelatin and acetic acid; the gelatin solution is slowly dropped into the butyl titanate alcoholic solution to obtain a sol solution; then the sol solution is aged and dried to obtain dry gel; the dry gel is put into distilled water for boiling; after filtration cleaning is executed, the product is cleaned through the alcohol and then is dried to obtain the anatase TiO2 nanocrystalline mesoporous microsphere. The preparation technology disclosed by the invention is simple and favorable for large-scale popularization and application, and a used solvent is safe and environment-friendly.

Description

technical field [0001] The invention belongs to the technical field of nanomaterial preparation, and in particular relates to a method for preparing anatase-type titanium dioxide nanocrystal mesoporous microspheres. Background technique [0002] Nano-titanium dioxide is widely used in the fields of new dye-sensitized solar cells and photocatalysis due to its non-toxicity, weather resistance, chemical stability, high photoelectrochemical reactivity and ultra-high specific surface area. The nano-size effect not only brings a large specific surface area, but also greatly shortens the migration distance of the photogenerated electron-hole pairs to the liquid-solid interface, and promotes the separation of the photogenerated electron-hole pairs, thereby improving the photoelectric conversion efficiency and the catalytic performance of the catalyst. Photocatalytic efficiency. Unfortunately, due to the small particle size, it is difficult to recycle for catalytic use, the particle...
