Description

technical field

[0001] The invention relates to a composite material, in particular to a core shell metal nano photocatalyst composite material and a manufacturing method thereof. Background technique

[0002] A catalyst is a chemical substance that itself can reduce the energy (activation energy) required for a chemical reaction to promote the occurrence of a chemical reaction or accelerate the rate of the reaction, but it does not change itself.

[0003] Photocatalysts use the energy of light sources of specific wavelengths to produce catalytic effects under the irradiation of light sources. These free radicals with strong oxidizing power can decompose almost all organic substances that are harmful to the human body or the environment, and make the surrounding oxygen and molecules excited into extremes. Active ·OH and ·O 2 Free radicals can sterilize, inhibit viruses, deodorize, and decompose organic matter.

[0004] Titanium Dioxide (TiO 2 ) is most often used as a cle...
