Problems solved by technology

However, although the built-in electric field formed by p-n can realize the separation of photogenerated carriers, the separation effect of the fixed built-in electric field will gradually decrease with the progress of the photocatalytic process, and the electric field at both ends of the p-n junction will gradually decrease. Charge separation, thereby inhibiting the separation of charges and reducing the photocatalytic (bactericidal) performance

Embodiment Construction

[0018] Such as figure 1 As shown, an antibacterial photocontact medium is active to visible light with a wavelength in the range of 380nm to 700nm.

[0019] The antibacterial photocontact medium includes piezoelectric material 2, which is a piezoelectric material 2 that has been polarized. The piezoelectric material 2 is selected from one or more of barium titanate, lead titanate, and zinc oxide.

[0020] The inner and outer sides of the piezoelectric material 2 are respectively provided with a porous metal oxide film 1, and the surface of the porous metal oxide film 1 is provided with metal particles. The metal particles are selected from the group consisting of cerium, magnesium, calcium, strontium, barium, radium, and combinations thereof The weight ratio of the weight of the metal particles to the weight of the porous metal oxide film 1 is 0.1:99.9 to 1:99.

[0021] The metal particles form an island-shaped discontinuous coating layer on the surface of the porous metal oxide fil...

Abstract

The invention provides an antibacterial light touch medium. The antibacterial light touch medium comprises a piezoelectric material, porous metal oxide films are arranged on the inner side and the outer side of the piezoelectric material respectively, metal particles are distributed on the surfaces of the porous metal oxide films, the piezoelectric material is subjected to polarization treatment,and the metal particles comprise at least one metal selected from cerium, magnesium, calcium, strontium, barium, radium and combinations of the cerium, the magnesium, the calcium, the strontium, the barium and the radium. The weight ratio of the metal particles to the porous metal oxide film is 0.1: 1. According to the photocatalyst, the piezoelectric material is wrapped by the porous metal oxidefilm, and the polarization characteristic of the piezoelectric material is utilized, so that the directional transmission effect of photon-generated carriers is favorably realized, the recombination of the photon-generated carriers can be reduced, and the photocatalytic sterilization efficiency of the prepared photocatalyst is further improved.

Description

Technical field [0001] The invention belongs to the technical field of light touch media, and specifically relates to an antibacterial light touch media. Background technique [0002] Photocatalyst is a substance that can promote photochemical reaction after being irradiated by light. In detail, after the photocatalyst material is irradiated by ultraviolet light or visible light, it forms electron hole pairs, which induce the medium (such as: air) in contact with the photocatalyst material. , Water, etc.) and then generate hydroxyl radicals or ozone, which use hydroxyl radicals or ozone to decompose bacteria and organic substances to achieve antibacterial and purification effects. Therefore, it is widely used in water treatment and air purification fields. [0003] Photocatalytic semiconductor materials can be divided into n-type semiconductors and p-type semiconductors according to the characteristics of carriers. Different types of semiconductor materials can be combined to pro...
