Abstract

The invention discloses a preparation method of a titanium oxide film electrode based on a titanium mesh. The method comprises the following steps: (1) the titanium mesh is cut into 7.5 cm*2.8 cm, sanded by sand paper, washed with distilled water and then ultrasonically cleaned with acetone for 20 min; (2) the titanium mesh is cleaned with ethanol and the distilled water for 20 min respectively and blow-dried; (3) a Ti target is presputtered with Ar in advance; (4) a film is formed on the surface of the titanium mesh with a high-vacuum DC magnetron sputtering method, and the preparation conditions are as follows: pure Ti serves as the target, the titanium mesh serves as a substrate, the temperature of the substrate is 280 DEG C, and the distance between the target and the substrate is 8.0cm; argon serves as working gas, oxygen serves as reaction gas, and the flow ratio is 15:20; the vacuum degree is 5.0*10<-4> Pa, the working air pressure is 1.0 Pa, the sputtering power is 100 W, andthe sputtering time is 60 min; (5) the titanium mesh and the film are annealed at constant temperature for 1 h, and the titanium oxide film electrode is obtained.

Description

technical field [0001] The invention relates to the technical field of titanium oxide thin film technology, in particular to a method for preparing a titanium oxide thin film electrode based on titanium mesh. Background technique [0002] Titanium oxide thin film electrodes are commonly used and effective photocatalysts in photocatalytic technology, which can effectively degrade organic pollutants. However, the current titanium oxide thin film electrodes generally use anodic oxidation, vapor deposition or sol-gel methods. To prepare titanium oxide thin film electrodes, the above-mentioned various methods have certain defects, such as complicated process, irregular and uniform shape, insufficient chemical activity of the prepared titanium oxide thin film electrodes, poor degradation effect, and slow reaction speed. Therefore, a new method is needed to prepare titanium oxide thin film electrodes with high catalytic activity. Contents of the invention [0003] The purpose of...
