Embodiment 1

[0078] In this embodiment, a titanium-oxygen material is prepared, and the specific process is as follows:

[0079] A1. Weigh 0.2g TiO 2 (10-25nm) into 40ml ethanol-water mixture with a volume ratio of 70% ethanol, ultrasonic for 30min;

[0080] A2. Pass N into the mixture obtained in step A1 2 , to exclude the oxygen dissolved in it, and seal it;

[0081] A3. Put the mixture obtained in step A2 into a beta ray radiation field, and accept a dose of 60.6kGy of radiation;

[0082] A4. Put the mixture obtained in step A3 into a gamma ray radiation field, and accept a dose of 30.6kGy of radiation;

[0083] A5. The solid product obtained in step A4 was repeatedly washed with ethanol and deionized water, and dried in vacuum to obtain a titanium-oxygen material. Examples 2-4 and Comparative Examples 1-6 respectively prepared a titanium-oxygen material, the specific difference from Example 1 is that the type of radiation field used in steps A3-A4 and the radiation dose received ar...

Abstract

The invention discloses a preparation method and application of a titanium-oxygen material. The preparation method of the titanium-oxygen material comprises the following steps: in an oxygen-free environment, radiating preparation raw materials by adopting charged particles and gamma ray in sequence. The preparation raw materials comprise a titanium oxide and a free radical quenching agent. According to the preparation method of the titanium-oxygen material, charged particle irradiation and gamma ray irradiation are sequentially carried out, so that oxygen vacancies are distributed on the bulk phase and the surface of the titanium-oxygen material, and the catalytic activity of the obtained titanium-oxygen material can be improved.

Description

technical field [0001] The invention belongs to the technical field of catalytic engineering, and in particular relates to a preparation method and application of a titanium-oxygen material. Background technique [0002] Environmental pollution and energy crisis are the key issues hindering the development of science and technology; photocatalytic technology is one of the effective ways to solve the above problems, and it is very important to develop efficient and economical photocatalysts. [0003] Titanium dioxide (TiO 2 ) is a kind of semiconductor material, which has the advantages of good photoelectrochemical stability, environmental friendliness, good biocompatibility, low cost and high redox ability, so it has great application potential in the fields of optoelectronics, biomedicine and photocatalysis. In the past few decades, it has received extensive attention from researchers. [0004] in TiO 2 The introduction of defects into nanomaterials can effectively broad...
