Technology for water
We provide solutions for water purification using nanotechnology. Our technology is characterized by uniformly coating each wire by growing nanocrystals such as photocatalyst titanium oxide on the surface of metal fine mesh such as stainless steel mesh. When a liquid such as water passes through a fine mesh, there is a high probability of contact between the nanocrystals and the substance in the fluid, making it possible to take full advantage of the catalytic action.
In particular, by controlling the crystal growth mode, a mesoscopic structure with a large surface area and high liquid permeability.1), which efficiently promotes chemical reactions targeting viruses, bacteria, etc. on a molecular scale, such as smells. In addition to being antibacterial and antiviral, we also have coating technology that is heat resistant, acid resistant, and alkali resistant.
1) A mesoscopic structure is a structure that is intermediate in size between a macroscopic structure and a microscopic structure. It often refers to structures with a size of about 10 – 100 nm.
Technology for air
Utilizing our specially shaped photocatalytic coating technology, we provide solutions for air purification.
Our technology is characterized by coatings that use photocatalysts to decompose odor molecules, etc., and to be antibacterial and antiviral. In addition to stainless steel mesh coating using nanotube-type titanium oxide, we also plan to release spray-type and paint-type coatings using sol (dispersion of titanium oxide fine particles) containing titanium oxide fine particles.
Technical consultation
When developing equipment incorporating our products, we accept paid technical consultations to make the most of the features of the products. We also provide simple technical information free of charge, so please feel free to contact us.
Product IntroductionProducts
Photocatalytic filter “eZov”
Make air and water beautiful!
High efficiency photocatalytic filter “eZov”
The photocatalytic effect is dramatically increased due to the large surface area, and
the decomposition efficiency of organic molecules is
greatly improved*
*Compared to existing flat photocatalysts
Existing titanium oxide is applied on a flat surface.
The wind flows over the surface.
It decomposes only the moment it touches the titanium oxide part.
Disassembly takes time in a closed space.
eZov’s titanium oxide is produced on a mesh.
Wind passes through the mesh.
The nanostructure captures viruses and odors and decomposes them without letting them go.
Decomposes in a short time even in open spaces.
Succeeded in growing nanostructured titanium oxide on mesh-like metal (stainless steel). A highly efficient photocatalytic filter has been created.
Stainless steel mesh (electron micrograph)

Features of stainless steel mesh with titanium oxide/zinc oxide nanostructured coating
The above is an electron microscope image of our photocatalyst-added stainless steel mesh.
The needle-shaped zinc oxide/titanium oxide nanostructure photocatalyst is evenly added to the stainless steel mesh. This is not a method of applying powder from the outside, but rather a method of growing the photocatalyst structure on the stainless steel mesh by itself through a chemical reaction, so it is possible to add a photocatalyst coating to meshes and other structures of various shapes according to the target fluid and flow rate.
Since general photocatalysts have a porous structure in which fine particles of about 10 nanometers are aggregated, it may not be possible to effectively utilize the deepest parts of the pores. However, this photocatalyst with a special needle-shaped structure has the great advantage that it takes a short time for molecules or viruses to be decomposed to move to deep parts and has a high effective surface area. In addition, because the needle-shaped structure is just under 1 micron thick, it is originally structured to easily capture viruses of about several hundred nanometers in size, and it is expected that it will be possible to decompose viruses with the viruses attached. (Currently, we are verifying this using viruses.)
Solve the problem of “viruses, bacteria, chemicals + odors” in the air and water with photocatalysts!
Moreover, it works using natural light, so no electricity is required!
(Solving issues for medical institutions, public facilities, livestock businesses, factories, mobility issues, etc.)
Benefits of eZov
- Viruses can be removed by ventilation alone.
- No electricity required as it uses natural light.
- No need for regular filter replacement or cleaning.
- Since it is made of metal, it has high security.
- has higher decomposition efficiency and lower manufacturing cost than existing photocatalytic filters.
For example, in this scene
- We want to suppress virus infections in both humans and livestock. Currently, ventilation is the basic method, and disinfection is carried out at a high cost.
- In addition, there is a need to more easily suppress infections, which can be done using air purifiers.
- No electricity required as it uses natural light.
- HEPA filters in air purifiers need to be replaced at regular intervals, so we want to eliminate that hassle.
- HEPA filters are only effective in closed spaces, but you want to remove viruses while ventilating the space.
- There are concerns about security with the current screen door, but I would like to ventilate without worrying about security.
