The term "nano" is circulating in the world, but it originally refers to a unit meaning "one billionth." Therefore, when you add "nano" to units like meters, seconds, liters, or grams, it indicates one billionth of that unit. However, for some reason, only the length unit with "nano" added to meters is receiving significant attention. One nanometer, commonly referred to as "1 nano," simply means one billionth of a meter. In this document, we will provide specific examples to explain its meaning. 【Contents】 ■ Overview ■ Example 1 ■ Example 2 ■ Example 3 ■ Size of photocatalysts ■ Interparticle bonding strength *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce a case where our company proposed photocatalysts for indoor deodorization. In the past, during tenant turnover, we have been replacing wallpaper and vinyl CF sheets on the floors as part of renovations and conducting cleaning. However, there are instances where lingering odors from daily life remain, making it challenging to address deodorization. We received inquiries asking if there are methods to eliminate such room odors. As a cost-effective solution, we proposed three methods: "applying photocatalysts not only to walls and floors but also to fabrics," "applying dark area photocatalysts in places where light does not reach," and "occasionally humidifying the space." 【Case Overview】 ■ Issues - There are instances where lingering odors from daily life remain, making deodorization challenging. - The types of odors mainly include musty smells, odors from food habits differing due to foreign nationals' diets, tobacco smells, and perfume-like odors from women. ■ Proposal - Apply photocatalysts not only to walls and floors but also to fabrics like curtains. - Apply dark area photocatalysts in places where light does not reach, such as inside closets, under the kitchen, and behind toilets. - Occasionally humidify the space. *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce the "Points to Note on the Photocatalytic Self-Cleaning Function" of Chemical Technology Co., Ltd. The self-cleaning function of photocatalysts depends on hydrophilicity. It only refers to the anti-fouling function against hydrophobic contaminants. When water is sprayed onto the photocatalytic surface with a mist sprayer, a water film spreads, confirming good hydrophilicity, which is a characteristic of the photocatalyst. [Features] ■ The self-cleaning function of photocatalysts depends on hydrophilicity ■ It only refers to the anti-fouling function against hydrophobic contaminants ■ When water is sprayed with a mist sprayer, a water film spreads, confirming good hydrophilicity ■ The self-cleaning effect is strictly proportional to hydrophilicity *For more details, please refer to the PDF document or feel free to contact us.

The deodorizing function of photocatalysts is almost proportional to the surface area, so applying them to materials with a larger surface area will increase their effectiveness. For example, smooth glass has a surface area of 1.3 m²/g, but even nylon, which has the smallest surface area, has an effective surface area more than ten times that. To achieve a noticeable deodorizing effect, it is recommended to apply "NFE2" to fibers with as large a surface area as possible. 【Application to Fibers】 <Type of Fiber: BET Adsorption Surface Area cm²/g> ■ Wool: 400–600 ■ Cotton: 60–120 ■ Polyester: 20–50 ■ Nylon: 15–50 ■ Glass t=3.0mm (for reference): 1.3 *For more details, please refer to the PDF materials or feel free to contact us.

Here are the capabilities that can only be realized with the photocatalyst "NFE2." It has a high and guaranteed safety for anti-mold and anti-algae effects, providing excellent self-cleaning effects not only for exteriors but also for interiors. It boasts high water resistance that can be applied even underwater and allows for low-temperature, short-time baking processes. Thanks to the product's super hydrophilicity, high antibacterial properties, affinity with the substrate at high temperatures, and active oxygen retention performance, it enables the creation of "anti-mold and anti-virus air conditioning filters," "algae-free aquariums," "curtains that instantly eliminate odors," and "stain-resistant exterior baked panels." This is an additional feature that we highly recommend for those struggling with differentiating their own products. [What can be realized] ■ Anti-mold and anti-virus air conditioning filters ■ Algae-free aquariums ■ Curtains that instantly eliminate odors ■ Stain-resistant exterior baked panels ■ Costumes that do not retain sweat odor ■ Mouse and mouse pads that do not get fingerprints *For more details, please refer to the PDF materials or feel free to contact us.

We would like to introduce our tangible photocatalyst, the "Photocatalytic Deodorizing Mat for Refrigerators." There have been questions such as, "Isn't it pointless to use a photocatalyst since the light goes out when the refrigerator door is closed?" but there is no need to worry. This deodorizing mat does not require constant illumination; a sunbath of about once a month is sufficient to maintain its performance. It can be said that this product fundamentally overturns the preconceived notion that "photocatalysts need constant light, especially for indoor use." 【Features】 ■ Does not require constant illumination ■ Activated sufficiently with about 30 minutes of sunlight once a month on sunny days ■ Activating it with a spray bottle to replenish moisture during sunbathing significantly enhances its effectiveness ■ Remarkably eliminates unpleasant odors from the refrigerator ■ The deodorizing mat can be used repeatedly and semi-permanently *For more details, please refer to the PDF document or feel free to contact us.

This document is a proposal on the use of photocatalysts for the removal of pathogens and viruses. The active oxygen generated by indoor photocatalysts is generally at a very low concentration, so it cannot eliminate pathogens and viruses on its own. Therefore, our company has successfully enhanced this function by combining copper ions and silver ions generated from metal particles, as well as iodine, which we have already introduced on our website.

Our company focuses on "metallic copper," which generates a large amount of copper ions (Cu2+), a powerful antibacterial and antiviral agent that is relatively harmless to the human body.
