specific Embodiment approach 1

[0023] Specific embodiment 1: This embodiment is a method for preparing a 1T phase molybdenum disulfide-supported titanium dioxide nanotube array, which is specifically carried out according to the following steps:

[0024] 1. Prepare titanium wire: Wind the titanium wire into a spiral shape, then ultrasonically clean it with acetone, ethanol and deionized water for 0.5h to 1h respectively, and finally place it in a drying oven to dry;

[0025] 2. Place the dried titanium wire in step 1 as the anode in the electrolytic cell, and the platinum mesh as the cathode in the electrolytic cell; the solute of the electrolyte is hydrofluoric acid, the solvent is dimethyl sulfoxide, and the hydrogen fluoride in the electrolyte is The mass fraction of the acid is 2% to 3%; it is oxidized at room temperature and under the condition of a constant voltage of DC power supply of 30V to 35V for 8h to 10h. After the oxidation is completed, it is taken out and dried to obtain an amorphous form bas...

specific Embodiment approach 2

[0028] Specific embodiment 2: The difference between this embodiment and specific embodiment 1 is that in step 1, the titanium wire is wound into a spiral shape, and then ultrasonically cleaned with acetone, ethanol and deionized water for 0.5h respectively, and finally placed in a drying box dry. Others are the same as the first embodiment.

specific Embodiment approach 3

[0029] Specific embodiment three: the difference between this embodiment and specific embodiment one or two is that: the solute of the electrolytic solution described in step one is hydrofluoric acid, the solvent is dimethyl sulfoxide, the quality of hydrofluoric acid in the electrolytic solution The score is 2%. Others are the same as those in Embodiment 1 or 2.

Abstract

The invention provides a preparation method and application of a 1T phase molybdenum disulfide supported titanium dioxide nanotube array, relates to a preparation method and application of a titaniumdioxide nanotube array, and aims to solve the technical problem that the current degradation effect on antibiotic wastewater is poor. The preparation method comprises the following steps of 1, preparation of titanium wires, 2, preparation of amorphous titanium dioxide, 3, annealing and 4, a hydrothermal reaction. The preparation method and application of the 1T phase molybdenum disulfide supportedtitanium dioxide nanotube array have the advantages that a composite material of the 1T phase molybdenum disulfide supported titanium dioxide nanotube array as a catalyst is applied to photoelectrocatalytic degradation of antibiotics in the antibiotic wastewater; under the action of sunlight and electricity, TiO2NTS of the prepared composite material can generate hydroxyl radicals to oxidize anddegrade antibiotic molecules, and 1T MoS2 can be rapidly reduced in the electrocatalytic environment, so that the antibiotic molecules are dehalogenated, thereby achieving the purpose of rapid degradation of pollutants, and being capable of degrading more than 95% of antibiotics within 2 h.

Description

technical field [0001] The invention relates to a preparation method and application of a titanium dioxide nanotube array. Background technique [0002] Since the introduction of penicillin in 1929, antibiotics have been instrumental in improving the health of humans and animals. Veterinary antibiotics are also commonly added to animal feed in some countries to improve growth rate and feed efficiency. Antibiotics for human and veterinary use are primarily excreted in urine and feces, with a significant fraction excreted in the unchanged active form. Antibiotic contamination is also present in different environmental areas such as WWTPs, livestock farms, river water and soil and groundwater. Residual antibiotics in the environment can adversely affect non-target organisms, contaminate food and drinking water supplies, and increase bacterial resistance. [0003] Florfenicol, as an antibiotic, is a new generation of amide alcohol semi-synthetic antibiotics developed by Seher...
