Problems solved by technology

Among them, photocatalytic degradation of organic pollutants is a green, economical and promising technology, among which TiO2 has received extensive attention because of its low cost, environmental friendliness, good stability, strong oxidation energy and Good corrosion resistance, but low quantum efficiency limits the practical application of TiO2
Through a lot of attempts, the photocatalytic performance of TiO2 has been significantly improved, but the introduction of foreign elements will generate additional impurities, which will affect the structure and properties of TiO2 itself
In addition, its complex preparation procedures and the need for special precursors will also increase the cost of commercialization

Abstract

The invention relates to a preparation method of a titanium dioxide surface heterojunction hybrid material, the preparation method comprises the following steps: preparing TiO2 {001} nanosheets by using a solvothermal method and taking titanium isopropylate as a precursor, taking isopropanol as a solvent and taking diethylenetriamine as a structure-directing agent, preparing TiO2 {100} by using a hydrothermal method, preparing {001} / {100} surface heterojunction by using a solvothermal method, and similarly using NaBH4 as a reducing agent, uniformly mixing NaBH4 and TiO2 by adopting a solid grinding method, and then calcining the mixture in an inert atmosphere at the temperature of 300 DEG C to synthesize the defect {100} / {001} surface heterojunction nano material. The synthetic route used in the invention is energy-saving, environment-friendly and efficient.

Description

technical field [0001] The invention relates to a preparation method of a titanium dioxide surface heterojunction hybrid material, belonging to the technical field of photocatalysts. Background technique [0002] The rapid development of modern industry consumes a lot of energy, but also causes serious environmental pollution. For example, industrial pollutants and discharged wastewater contain a large amount of harmful substances such as heavy metals and organic macromolecules, which seriously endanger human health and affect the sustainable development of the economy. In order to solve this problem, scientific researchers have extensively developed various new technologies to control the environment, and develop clean energy to ensure the sustainable development of the national economy. Among them, photocatalytic degradation of organic pollutants is a green, economical and promising technology, among which TiO2 has received extensive attention because of its low cost, env...
