Embodiment 1

[0022] Example 1 The non-precious metal chlorine evolution catalyst electrode provided in this example mainly consists of a titanium mesh and a thin film catalyst Co(OH) on the surface of the titanium mesh. 2 constitute.

[0023] The non-noble metal chlorine analysis catalyst electrode of this embodiment is prepared by a cathode constant voltage electrodeposition method, which specifically includes the following steps:

[0024] (1) Cut the titanium mesh with a purity of 99.99% by 1cm×1cm, and rinse the surface of the titanium mesh with distilled water. After rinsing, use absolute ethanol to ultrasonically clean it for 20 minutes. After cleaning, pour out the absolute ethanol and replace it with distilled water for 20 minutes of ultrasonic cleaning. After cleaning, put it in an oven at 60 °C to make the surface dry quickly .

[0025] (2) Clamp the treated titanium mesh with the electrode holder as the working electrode, and the platinum mesh and saturated calomel electrode as...

Abstract

The invention belongs to the technical field of marine fouling protection, and particularly relates to a non-noble metal chlorine evolution catalyst electrode and a preparation method thereof. The non-noble metal chlorine evolution catalyst electrode comprises a substrate, and a catalyst Co(OH)2 is deposited on the surface of the substrate. The electrode loaded with the non-noble metal catalyst for chlorine evolution through seawater electrolysis can remarkably improve the seawater electrolysis efficiency. The catalyst can generate sufficient and controllable available chlorine with a biological killing effect under the condition of short-time and small-voltage electrification, so that the antifouling effect is achieved.

Description

technical field [0001] The invention belongs to the technical field of marine pollution protection, and in particular relates to a non-precious metal chlorine analysis catalyst electrode and a preparation method thereof. Background technique [0002] The problem of marine biofouling is a problem that has plagued mankind for a long time. It has brought many negative effects to various equipment used in the ocean exploration process, such as reducing the speed of ships, blocking cooling water channels, and affecting the data collection of underwater sensors. accuracy. This has also stimulated the development of anti-fouling technologies for marine equipment. At present, there are three main methods for antifouling on the market: (1) purely mechanical equipment, such as scrapers; (2) leaching systems based on copper and tributyltin biocides; (3) based on partial electrolysis of seawater activity Chlorine-generated biocide generation system. Mechanical antifouling requires ma...
