Brief introduction of project results

The invention relates to a light-driven oxygen and antibacterial active oxygen releasing body and a preparation process.

Advantages of this product:About domestic antibacterial, we generally use hydrogen peroxide oxidation, chlorine-containing antibacterial agents and other chemical agents to achieve antibacterial effects, but antimicrobials can remain in the environment and in food.

This invention: 

1) Visible light drives the conversion of water into oxygen and hydroxyl free radicals, and it has spectral antibacterial and antiviral effects;

2) Non-chemical contact antibacterial; 

3) No antimicrobial residues; 

4) An environmentally-friendly solid antibacterial agents.

Performance indicators

1) Particle size 100-400 nm,

2) LED lamp (4 w) irradiates 5 mg sample for 1 hour to produce 140 micromoles of oxygen and active oxygen (hydroxyl radical and superoxide ion).

3) Sample recovery and reuse.

Scope of application and market prospects

Preparation of antibacterial and antiviral films as antibacterial agents for clothing, environmental and food packaging, especially suitable for low oxygen environment oxygen environmentally-friendly solid antibacterial.

Investment estimates

Equipment: conventional oven, reactor.

Main raw materials: iron salt and p-aminobenzoic acid.

Means of cooperation

Transfer of patent.
