Abstract

An electrolysis electrode and a preparation method therefor, an electrolysis apparatus, and a clothing treatment device. The electrolysis electrode includes a substrate, a transition layer, and an electrode catalytic material layer, and the transition layer is attached to the surface of the substrate, the electrode catalytic material layer is attached to the surface of the transition layer, and the thickness of the transition layer satisfies that: electrons can pass through the transition layer. The transition layer of the electrolysis electrode is relatively thin, so that electrons can pass through the transition layer due to a quantum tunneling effect, and thus the electrocatalytic performance of the electrolysis electrode is basically not affected. Furthermore, the transition layer plays the role of transition connection, and can greatly improve the phenomenon of cracks in the electrode catalytic material layer.

First claim

What is claimed is:

1. A clothing treatment device, comprising an outer cylinder, an inner cylinder rotatably arranged in the outer cylinder, and an electrolysis apparatus; wherein
the electrolysis apparatus is arranged between the inner cylinder and the outer cylinder;
the electrolysis apparatus comprises an anode made of an electrolysis electrode;
the electrolysis electrode comprises a base body, a transition layer attaching to a surface of the base body, and an electrode catalytic material layer attaching to a surface of the transition layer; and
the transition layer has a thickness allowing electrons to penetrate through the transition layer.

2. The clothing treatment device of claim 1 , wherein the thickness of the transition layer is 1-10 nm.

3. The clothing treatment device of claim 1 , wherein the base body is a titanium base body; and/or, the transition layer is an aluminum oxide transition layer.

4. The clothing treatment device of claim 1 , wherein the electrode catalytic material layer is a platinum layer plated on the surface of the transition layer, or a boron-doped diamond film material deposited on the surface of the transition layer.

5. The clothing treatment device of claim 1 , wherein the electrode catalytic material layer is a nano hybrid coating formed by a stable oxide material and an active oxide material together; the stable oxide material comprises one or more of: silicon dioxide, tantalum pentoxide, cobalt dioxide, tungsten trioxide, or ruthenium dioxide; and the active oxide material comprises one or more of: an iridium-based oxide, a tin-based oxide, or a lead-based oxide.

6. The clothing treatment device of claim 5 , wherein a weight ratio of the active oxide material to the stable oxide material is (0.2-0.9):(0.1-0.8).

7. The clothing treatment device of claim 1 , wherein the electrolysis apparatus further comprises a cathode made of a metal material or is an electrolysis electrode, the electrolysis electrode comprising:
a base body, a transition layer attaching to a surface of the base body, and an electrode catalytic material layer attaching to a surface of the transition layer, wherein the transition layer has a thickness allowing electrons to penetrate through the transition layer.
