Biocera-T (TiO2) Photocatalyst for Air Filter

Volatile Organic Compounds (VOCs) are hazardous chemicals with high vapor pressure at room temperature. They pose numerous health risks to humans and are harmful to the environment. High concentrations of VOCs, especially indoors, can be toxic. Biocera's photocatalyst coating technology has enabled building materials to have advanced functions such as deodorizing and anti-fouling properties.

Photocatalysts act as oxidizing agents when activated by ultraviolet rays, particularly sunlight. When photocatalyst titanium dioxide (TiO2) captures ultraviolet light (ranging from UV-A to UV-B, with the most efficient range being 350-380 nanometers), it generates activated oxygen from water or oxygen in the air. This process is similar to photosynthesis, where chlorophyll captures sunlight to convert water and carbon dioxide into oxygen and glucose. The activated oxygen produced by TiO2 is powerful enough to oxidize and decompose organic materials and odor-causing gases. Our photocatalytic titanium dioxide can break down various substances that produce odors, mainly organic compounds, into carbon dioxide and water through light irradiation. This technology not only helps in reducing unpleasant smells but also contributes to maintaining a cleaner and healthier indoor environment.

BIOCERA T, Photocatalyst Filter

The working principle of semiconductor photocatalysts is quite similar to the photosynthesis process in plants. When light shines on the surface of the semiconductor, it generates electrons and holes, giving it a strong oxidation and reduction capacity. This makes it highly effective at decomposing and removing a variety of substances that may adhere to the surface, such as odor-causing compounds, organic pollutants, bacteria, mold, dust, and oil. These substances are broken down into harmless carbon dioxide and water.

One of the major advantages of this technology is its energy efficiency. It can operate effectively with just sunlight or fluorescent light, making it very economical. Additionally, the semiconductor photocatalyst itself, particularly when using titanium dioxide (TiO2), can maintain its effectiveness almost indefinitely, providing a semi-permanent solution. Titanium dioxide is also known to be safe for human use, as it is commonly used as a food additive. This combination of effectiveness, sustainability, and safety makes semiconductor photocatalysts an excellent choice for maintaining cleaner and healthier environments.

What is Semiconductive Photocatalyst +

The photocatalyst is defined as "acceleration by the presence of a catalyst." This definition includes photosensitization, a process by which a photochemical alteration occurs in one molecular entity as a result of initial absorption of radiation by another molecular entity called the photosensitized. We call this "photosensitized the photocatalyst," but it excludes the photo acceleration of a stoichiometric thermal reaction (exergonic or endergonic) irrespective of whether it occurs in homogeneous solution or at the surface of an illuminated electrode. Nano-titania Photocatalyst acts as an oxidizing agent when activated by ultraviolet ray, especially sunlight.
