Abstract

The invention discloses a heterostructure material In2O3 / In2TiO5, as well as application and a preparation method thereof. The heterostructure material In2O3 / In2TiO5 comprises In2O3 and In2TiO5, and is prepared by the following steps: using glycine, indium nitrate, butyl titanate and nitrocellulose as raw materials, wherein the ratio of indium nitrate to butyl titanate is 2 to 1, and performing high-temperature roasting. The heterostructure material In2O3 / In2TiO5 is prepared for the first time, is used as a photocatalytic material, is mild in synthesis condition, stable in performance, and high in activity, can be repeatedly used, can be used for photolysis and purification of toxic and harmful chemical substances such as antibiotics or dyes in wastewater in UV-light and visible light, solves the technical problem that a traditional photocatalyst cannot realize photolysis and purification of toxic and harmful chemical substances such as antibiotics or dyes in wastewater in visible light, and enriches the varieties of photocatalysts.

Description

Technical field [0001] The invention belongs to the technical field of material preparation, and specifically relates to a heterostructure material In 2 O 3 / In 2 TiO 5 , Also related to the above-mentioned heterostructure material In 2 O 3 / In 2 TiO 5 The application and preparation method. Background technique [0002] With the continuous acceleration of the process of industrialization and the expansion of the scope of human life, the problem of water pollution has become increasingly serious, and the discharge of a large amount of waste water has made the quality of people's living environment worse. Among them, antibiotic wastewater is difficult to achieve traditional biodegradation because it contains biologically toxic substances, which has become a major problem in the field of water treatment. As one of the advanced oxidation technologies, the photocatalytic method is widely used in the application research of antibiotic degradation. Titanate nanomaterials have high mec...
