Method for preparing loaded nano titanium dioxide photocatalysis film

Abstract

This invention relates to a sol to gel method to process load nanometer titania effective light catalyzer thin film process method, which belongs to light catalyzer materials chemical technique field and comprises the following steps: using the pure titanic acid butonate and absolute ethyl alcohol, aminoethyl alcohol, water, poly-glycol 600 as materials; getting transparent stable light yellow titania sol through common temperature chemical reaction; then adopting the dipping and lifting method to load titania thin film on metal wire surface; finally burning in Muffle furnace under temperature of 450íµ to 550íµ to get the light catalyzer thin film.

Description

technical field

[0001] The invention relates to a method for preparing a loaded nano titanium dioxide 2 high-efficiency photocatalytic film by using a sol-gel method, and belongs to the technical field of photocatalytic material chemistry and chemical engineering. Background technique

[0002] In recent years, with the increasingly serious environmental problems worldwide, the use of TiO 2 The use of photocatalysts for environmental purification has attracted extensive attention. Currently, TiO 2 The application of photocatalyst mainly focuses on the purification and treatment of water and air, TiO 2 Photocatalytic oxidation can effectively remove toxic and harmful substances in air and water without secondary pollution. It is an environmentally friendly catalytic purification technology in the 21st century. Under the action of light, the strong oxidizing groups generated on the surface of semiconductor materials are used to oxidize and degrade most toxic and harmful orga...
