Abstract

The invention discloses a preparation method of a hydrophobic TiO2 visible-light catalyst. The hydrophobic TiO2 composite visible-light catalyst with high adsorption and wide spectral response is prepared by utilizing the strong adsorption property of hydrophobic attapulgite after being irradiated by high-power electron beams and the doping vario-property of migrating metal cations on the surfaceof the attapulgite, and the problems that a TiO2 photocatalyst has no adsorption or concentration capacity for strongly hydrophobic organic pollutants and is narrow in the spectral response range aresolved. The novel hydrophobic TiO2 visible-light catalyst material has the capacity of efficient concentration of the strongly hydrophobic organic pollutants and visible light degradation, and can beused for light degradation of indoor and industrial low-concentration VOCs (volatile organic chemicals) and water bodies and strongly hydrophobic organic matters in soil.

Description

technical field

[0001] The invention belongs to the technical field of preparation of visible light-responsive photocatalytic materials, and specifically relates to a high-adsorption performance and wide-spectrum hydrophobic TiO 2 Preparation method of visible light catalyst. Background technique

[0002] Titanium-based semiconductors are important materials in the field of photocatalysis and can be widely used in environmental and energy fields such as catalytic degradation and hydrogen production. However, the spectral response range of titanium-based semiconductors is narrow, and only 5% of the ultraviolet light in the solar spectrum can be used, resulting in a solar energy utilization rate of only about 1%. Subsequently, workers in the field also developed new visible light-responsive titanium-based photocatalysts modified by noble metal deposition, semiconductor recombination or dye photosensitization, but these modified titanium-based photocatalytic materials have low...
