The present invention provides a kind of light catalyst composition, mainly with titanium dioxide, graphene and light-guide material, wherein light
Leading material is for silica, quartz, glass, guide-lighting plastics or guide-lighting mineral.The ratio of components of light catalyst composition of the invention
Example is that 60~70wt% is accounted for for titanium dioxide, and graphene accounts for 15~20wt% and light-guide material accounts for 15~20wt%.
The present invention further provides a kind of air filtration structure, is light catalyst composition and substrate, wherein photocatalyst group
It closes object and is provided at substrate surface.Further it is wherein the combination to be sintered, be coated with or both, is set to substrate surface.
Substrate is reticular structure, can be flannelette, sponge, metal, polymer, composite material or stainless steel etc..
Light catalyst composition of the invention is the structure with graphene as carrier using titanium dioxide maintenance decorations, by two
The partial size of titanium oxide is maintained at 10nm (nanometer) hereinafter, furthermore more even 7nm (nanometer) is hereinafter, recycle the refraction of light-guide material
Light and reflection light characteristic allow more ultraviolet lights or blue outer luminous energy to expose to titanium dioxide, to improve the sky of light catalyst composition
Gas detergent power.
Above-listed detailed description is illustrating for a possible embodiments of the invention, and only the embodiment is not to limit
The scope of the patents of the invention is made, all equivalence enforcements or change without departing from carried out by technical spirit of the present invention are intended to be limited solely by this case
The scope of the patents in.
In conclusion this case not only really belongs to innovation in the kenel of space, and increase relative to existing article above-mentioned more
Item effect.
Detailed description of the invention
Fig. 1 is the schematic diagram of air filtration structure of the invention；
Fig. 2 is the schematic diagram of air filtration structure of the invention；
Attached drawing mark:
100 be compound, and 200 be light-guide material, and 300 be substrate, and 400 be ultraviolet light.
Specific embodiment
For benefit, your juror understands technical characteristic of the invention, content and advantage and its attainable effect, hereby will
The present invention cooperates attached drawing, and detailed description are as follows with the expression-form of embodiment, and wherein used schema, purport are only
Signal and aid in illustrating book and be used, actual proportions and precisely configuration after may not implementing for the present invention, therefore not should appended figure
The ratio of formula and configuration relation interpret, limits the invention to interest field in actual implementation, and conjunction is first chatted bright.
Fig. 1 and Fig. 2 is please referred to, is the schematic diagram of air filtration structure, it is main comprising utilizing two as carrier with graphene
Titanium oxide is compound 100, light-guide material 200 and the substrate 300 of the structure of modification, and wherein light-guide material 200 is titanium dioxide
